Certain languages allow direct addressing of memory locations and do not automatically ensure that these locations are valid for the memory buffer that is being referenced. This can cause read or write operations to be performed on memory locations that may be associated with other variables, data structures, or internal program data.
As a result, an attacker may be able to execute arbitrary code, alter the intended control flow, read sensitive information, or cause the system to crash.

Certain languages allow direct addressing of memory locations and do not automatically ensure that these locations are valid for the memory buffer that is being referenced. This can cause read or write operations to be performed on memory locations that may be associated with other variables, data structures, or internal program data.
As a result, an attacker may be able to execute arbitrary code, alter the intended control flow, read sensitive information, or cause the system to crash.

Certain languages allow direct addressing of memory locations and do not automatically ensure that these locations are valid for the memory buffer that is being referenced. This can cause read or write operations to be performed on memory locations that may be associated with other variables, data structures, or internal program data.
As a result, an attacker may be able to execute arbitrary code, alter the intended control flow, read sensitive information, or cause the system to crash.

A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.

A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.

XML documents optionally contain a Document Type Definition (DTD), which, among other features, enables the definition of XML entities. It is possible to define an entity by providing a substitution string in the form of a URI. The XML parser can access the contents of this URI and embed these contents back into the XML document for further processing.
By submitting an XML file that defines an external entity with a file:// URI, an attacker can cause the processing application to read the contents of a local file. For example, a URI such as "file:///c:/winnt/win.ini" designates (in Windows) the file C:\Winnt\win.ini, or file:///etc/passwd designates the password file in Unix-based systems. Using URIs with other schemes such as http://, the attacker can force the application to make outgoing requests to servers that the attacker cannot reach directly, which can be used to bypass firewall restrictions or hide the source of attacks such as port scanning.
Once the content of the URI is read, it is fed back into the application that is processing the XML. This application may echo back the data (e.g. in an error message), thereby exposing the file contents.

The simplest way data corruption may occur involves the system's reuse of the freed memory. Use-after-free errors have two common and sometimes overlapping causes:
Error conditions and other exceptional circumstances.
Confusion over which part of the program is responsible for freeing the memory.
In this scenario, the memory in question is allocated to another pointer validly at some point after it has been freed. The original pointer to the freed memory is used again and points to somewhere within the new allocation. As the data is changed, it corrupts the validly used memory; this induces undefined behavior in the process.
If the newly allocated data chances to hold a class, in C++ for example, various function pointers may be scattered within the heap data. If one of these function pointers is overwritten with an address to valid shellcode, execution of arbitrary code can be achieved.

When mergeable buffer is enabled, we try to set the num_buffers after
the virtqueue elem has been unmapped. This will lead several issues,
E.g a use after free when the descriptor has an address which belongs
to the non direct access region. In this case we use bounce buffer
that is allocated during address_space_map() and freed during
address_space_unmap().
Fixing this by storing the elems temporarily in an array and delay the
unmap after we set the the num_buffers.
This addresses CVE-2021-3748.

The bug is an uninitialized memory read, along the translate_fail
path, which results in garbage being read from iotlb_to_section,
which can lead to a crash in io_readx/io_writex.
The bug may be fixed by writing any value with zero
in ~TARGET_PAGE_MASK, so that the call to iotlb_to_section using
the xlat'ed address returns io_mem_unassigned, as desired by the
translate_fail path.
It is most useful to record the original physical page address,
which will eventually be logged by memory_region_access_valid
when the access is rejected by unassigned_mem_accepts.

currently a malicious client could define a payload
size of 2^32 - 1 bytes and send up to that size of
data to the vnc server. The server would allocated
that amount of memory which could easily create an
out of memory condition.
This patch limits the payload size to 1MB max.

In order to prevent /proc/self/fd escapes a temporary directory is
created where /proc/self/fd is bind-mounted. This doesn't work on
read-only file systems.
Avoid the temporary directory by bind-mounting /proc/self/fd over /proc.
This does not affect other processes since we remounted / with MS_REC |
MS_SLAVE. /proc must exist and virtiofsd does not use it so it's safe to
do this.
Path traversal can be tested with the following function:
static void test_proc_fd_escape(struct lo_data *lo)
{
int fd;
int level = 0;
ino_t last_ino = 0;
fd = lo->proc_self_fd;
for (;;) {
struct stat st;
if (fstat(fd, &st) != 0) {
perror("fstat");
return;
}
if (last_ino && st.st_ino == last_ino) {
fprintf(stderr, "inode number unchanged, stopping\n");
return;
}
last_ino = st.st_ino;
fprintf(stderr, "Level %d dev %lu ino %lu\n", level,
(unsigned long)st.st_dev,
(unsigned long)last_ino);
fd = openat(fd, "..", O_PATH | O_DIRECTORY | O_NOFOLLOW);
level++;
}
}
Before and after this patch only Level 0 is displayed. Without
/proc/self/fd bind-mount protection it is possible to traverse parent
directories.

within the Bounds of a Memory Buffer | The software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. |
Certain languages allow direct addressing of memory locations and do not automatically ensure that these locations are valid for the memory buffer that is being referenced. This can cause read or write operations to be performed on memory locations that may be associated with other variables, data structures, or internal program data.
As a result, an attacker may be able to execute arbitrary code, alter the intended control flow, read sensitive information, or cause the system to crash.

There are many different kinds of mistakes that introduce information exposures. The severity of the error can range widely, depending on the context in which the product operates, the type of sensitive information that is revealed, and the benefits it may provide to an attacker. Some kinds of sensitive information include:
private, personal information, such as personal messages, financial data, health records, geographic location, or contact details
system status and environment, such as the operating system and installed packages
business secrets and intellectual property
network status and configuration
the product's own code or internal state
metadata, e.g. logging of connections or message headers
indirect information, such as a discrepancy between two internal operations that can be observed by an outsider
Information might be sensitive to different parties, each of which may have their own expectations for whether the information should be protected. These parties include:
the product's own users
people or organizations whose information is created or used by the product, even if they are not direct product users
the product's administrators, including the admins of the system(s) and/or networks on which the product operates
the developer
Information exposures can occur in different ways:
the code explicitly inserts sensitive information into resources or messages that are intentionally made accessible to unauthorized actors, but should not contain the information - i.e., the information should have been "scrubbed" or "sanitized"
a different weakness or mistake indirectly inserts the sensitive information into resources, such as a web script error revealing the full system path of the program.
the code manages resources that intentionally contain sensitive information, but the resources are unintentionally made accessible to unauthorized actors. In this case, the information exposure is resultant - i.e., a different weakness enabled the access to the information in the first place.
It is common practice to describe any loss of confidentiality as an "information exposure," but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read. CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.

This can have security implications when the expected synchronization is in security-critical code, such as recording whether a user is authenticated or modifying important state information that should not be influenced by an outsider.
A race condition occurs within concurrent environments, and is effectively a property of a code sequence. Depending on the context, a code sequence may be in the form of a function call, a small number of instructions, a series of program invocations, etc.
A race condition violates these properties, which are closely related:
Exclusivity - the code sequence is given exclusive access to the shared resource, i.e., no other code sequence can modify properties of the shared resource before the original sequence has completed execution.
Atomicity - the code sequence is behaviorally atomic, i.e., no other thread or process can concurrently execute the same sequence of instructions (or a subset) against the same resource.
A race condition exists when an "interfering code sequence" can still access the shared resource, violating exclusivity. Programmers may assume that certain code sequences execute too quickly to be affected by an interfering code sequence; when they are not, this violates atomicity. For example, the single "x++" statement may appear atomic at the code layer, but it is actually non-atomic at the instruction layer, since it involves a read (the original value of x), followed by a computation (x+1), followed by a write (save the result to x).
The interfering code sequence could be "trusted" or "untrusted." A trusted interfering code sequence occurs within the program; it cannot be modified by the attacker, and it can only be invoked indirectly. An untrusted interfering code sequence can be authored directly by the attacker, and typically it is external to the vulnerable program.
| https://cwe.mitre.org/data/definitions/362.html | 0 | Lev Stipakov | 2020-04-15 10:30:17+03:00 | Fix illegal client float (CVE-2020-11810)
There is a time frame between allocating peer-id and initializing data
channel key (which is performed on receiving push request or on async
push-reply) in which the existing peer-id float checks do not work right.
If a "rogue" data channel packet arrives during that time frame from
another address and with same peer-id, this would cause client to float
to that new address. This is because:
- tls_pre_decrypt() sets packet length to zero if
data channel key has not been initialized, which leads to
- openvpn_decrypt() returns true if packet length is zero,
which leads to
- process_incoming_link_part1() returns true, which
calls multi_process_float(), which commits float
Note that problem doesn't happen when data channel key is initialized,
since in this case openvpn_decrypt() returns false.
The net effect of this behaviour is that the VPN session for the
"victim client" is broken. Since the "attacker client" does not have
suitable keys, it can not inject or steal VPN traffic from the other
session. The time window is small and it can not be used to attack
a specific client's session, unless some other way is found to make it
disconnect and reconnect first.
CVE-2020-11810 has been assigned to acknowledge this risk.
Fix illegal float by adding buffer length check ("is this packet still
considered valid") before calling multi_process_float().

Malformed input data on the service pipe towards the OpenVPN interactive
service (normally used by the OpenVPN GUI to request openvpn instances
from the service) can result in a double free() in the error handling code.
This usually only leads to a process crash (DoS by an unprivileged local
account) but since it could possibly lead to memory corruption if
happening while multiple other threads are active at the same time,
CVE-2018-9336 has been assigned to acknowledge this risk.
Fix by ensuring that sud->directory is set to NULL in GetStartUpData()
for all error cases (thus not being free()ed in FreeStartupData()).
Rewrite control flow to use explicit error label for error exit.

test you could use any Linux guest for this test.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

This patch aims to fix a potential DDoS problem that can be caused
in the server quering repetitive non-existent resources.
When serving a static file, the core use Vhost FDT mechanism, but if
it sends a static error page it does a direct open(2). When closing
the resources for the same request it was just calling mk_vhost_close()
which did not clear properly the file descriptor.
This patch adds a new field on the struct session_request called 'fd_is_fdt',
which contains MK_TRUE or MK_FALSE depending of how fd_file was opened.
Thanks to Matthew Daley <[email protected]> for report and troubleshoot this
problem.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

This patch aims to fix a potential DDoS problem that can be caused
in the server quering repetitive non-existent resources.
When serving a static file, the core use Vhost FDT mechanism, but if
it sends a static error page it does a direct open(2). When closing
the resources for the same request it was just calling mk_vhost_close()
which did not clear properly the file descriptor.
This patch adds a new field on the struct session_request called 'fd_is_fdt',
which contains MK_TRUE or MK_FALSE depending of how fd_file was opened.
Thanks to Matthew Daley <[email protected]> for report and troubleshoot this
problem.

not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. |
Input validation is a frequently-used technique
for checking potentially dangerous inputs in order to
ensure that the inputs are safe for processing within the
code, or when communicating with other components. When
software does not validate input properly, an attacker is
able to craft the input in a form that is not expected by
the rest of the application. This will lead to parts of the
system receiving unintended input, which may result in
altered control flow, arbitrary control of a resource, or
arbitrary code execution.
Input validation is not the only technique for
processing input, however. Other techniques attempt to
transform potentially-dangerous input into something safe, such
as filtering (CWE-790) - which attempts to remove dangerous
inputs - or encoding/escaping (CWE-116), which attempts to
ensure that the input is not misinterpreted when it is included
in output to another component. Other techniques exist as well
(see CWE-138 for more examples.)
Input validation can be applied to:
raw data - strings, numbers, parameters, file contents, etc.
metadata - information about the raw data, such as headers or size
Data can be simple or structured. Structured data
can be composed of many nested layers, composed of
combinations of metadata and raw data, with other simple or
structured data.
Many properties of raw data or metadata may need
to be validated upon entry into the code, such
as:
specified quantities such as size, length, frequency, price, rate, number of operations, time, etc.
implied or derived quantities, such as the actual size of a file instead of a specified size
indexes, offsets, or positions into more complex data structures
symbolic keys or other elements into hash tables, associative arrays, etc.
well-formedness, i.e. syntactic correctness - compliance with expected syntax
lexical token correctness - compliance with rules for what is treated as a token
specified or derived type - the actual type of the input (or what the input appears to be)
consistency - between individual data elements, between raw data and metadata, between references, etc.
conformance to domain-specific rules, e.g. business logic
equivalence - ensuring that equivalent inputs are treated the same
authenticity, ownership, or other attestations about the input, e.g. a cryptographic signature to prove the source of the data
Implied or derived properties of data must often
be calculated or inferred by the code itself. Errors in
deriving properties may be considered a contributing factor
to improper input validation.
Note that "input validation" has very different
meanings to different people, or within different
classification schemes. Caution must be used when
referencing this CWE entry or mapping to it. For example,
some weaknesses might involve inadvertently giving control
to an attacker over an input when they should not be able
to provide an input at all, but sometimes this is referred
to as input validation.
Finally, it is important to emphasize that the
distinctions between input validation and output escaping
are often blurred, and developers must be careful to
understand the difference, including how input validation
is not always sufficient to prevent vulnerabilities,
especially when less stringent data types must be
supported, such as free-form text. Consider a SQL injection
scenario in which a person's last name is inserted into a
query. The name "O'Reilly" would likely pass the validation
step since it is a common last name in the English
language. However, this valid name cannot be directly
inserted into the database because it contains the "'"
apostrophe character, which would need to be escaped or
otherwise transformed. In this case, removing the
apostrophe might reduce the risk of SQL injection, but it
would produce incorrect behavior because the wrong name
would be recorded.

This patch aims to fix a potential DDoS problem that can be caused
in the server quering repetitive non-existent resources.
When serving a static file, the core use Vhost FDT mechanism, but if
it sends a static error page it does a direct open(2). When closing
the resources for the same request it was just calling mk_vhost_close()
which did not clear properly the file descriptor.
This patch adds a new field on the struct session_request called 'fd_is_fdt',
which contains MK_TRUE or MK_FALSE depending of how fd_file was opened.
Thanks to Matthew Daley <[email protected]> for report and troubleshoot this
problem.

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems.
It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.

that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. | An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.

| Out-of-bounds Read | The software reads data past the end, or before the beginning, of the intended buffer. | Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.
