Multiple heap-based buffer overflow vulnerabilities may be exploited by opening specially crafted project files that may overflow the heap, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.CVE-2020-16207 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). An out-of-bounds read vulnerability may be exploited by processing specially crafted project files, which may allow an attacker to read information.CVE-2020-16211 has been assigned to this vulnerability. A CVSS v3 base score of 3.3 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N). Processing specially crafted project files lacking proper validation of user supplied data may cause the system to write outside the intended buffer area, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.CVE-2020-16213 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Processing specially crafted project files lacking proper validation of user supplied data may cause a type confusion condition, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.CVE-2020-16229 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Processing specially crafted project files lacking proper validation of user supplied data may cause a stack-based buffer overflow, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.CVE-2020-16215 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). A double free vulnerability caused by processing specially crafted project files may allow remote code execution, disclosure/modification of information, or cause the application to crash.CVE-2020-16217 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
