Description

This security bulletin contains information about 3 vulnerabilities.


1) Reachable Assertion (CVE-ID: CVE-2022-42010)

CWE-ID: CWE-617 - Reachable Assertion

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a reachable assertion in debug builds caused by a syntactically invalid type signature with incorrectly nested parentheses and curly brackets. A local user can perform a denial of service (DoS) attack.


2) Out-of-bounds read (CVE-ID: CVE-2022-42011)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error caused by an invalid array of fixed-length elements where the length of the array is not a multiple of the length of the element. A local user can trigger an out-of-bounds read and gain access to sensitive information.


3) Use-after-free (CVE-ID: CVE-2022-42012)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error caused by a message in non-native endianness with out-of-band Unix file descriptors. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
