A use after free vulnerability may be exploited when a valid user opens a malformed project file, which may allow arbitrary code execution.CVE-2021-38438 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). The affected product lacks proper validation of user-supplied data when parsing project files, which could result in an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code.CVE-2021-38426 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). The affected product lacks proper validation of user-supplied data when parsing project files, which could result in an unexpected sign extension. An attacker could leverage this vulnerability to execute arbitrary code.CVE-2021-38434 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). The affected product lacks proper validation of user-supplied data when parsing project files, which could result in a stack-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code.CVE-2021-38430 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). The affected product lacks proper validation of user-supplied data when parsing project files, which could result in a memory-corruption condition. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.CVE-2021-38436 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). The affected product lacks proper validation of user-supplied data when parsing project files, which could result in a heap-corruption condition. An attacker could leverage this vulnerability to execute code in the context of the current process.CVE-2021-38442 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). The affected product is vulnerable to an out-of-bounds read, which may allow an attacker to read unauthorized information.CVE-2021-38440 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).
