macOS 12.x < 12.6.2 Multiple Vulnerabilities (HT213533)

critical Nessus Plugin ID 168669

Language:

Synopsis

The remote host is missing a macOS update that fixes multiple vulnerabilities

Description

The remote host is running a version of macOS / Mac OS X that is 12.x prior to 12.6.2. It is, therefore, affected by multiple vulnerabilities:

 - An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault. (CVE-2022-40303)

 - An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. (CVE-2022-40304)

 - The issue was addressed with improved memory handling. (CVE-2022-32942, CVE-2022-42840, CVE-2022-42842, CVE-2022-42845, CVE-2022-42854)

 - A logic issue was addressed with improved checks. (CVE-2022-42821)

 - A type confusion issue was addressed with improved checks. (CVE-2022-42841)

 - A logic issue was addressed with improved state management. (CVE-2022-42855)

 - This issue was addressed with improved checks. (CVE-2022-42861)

 - A race condition was addressed with improved state handling. (CVE-2022-42864)

 - A race condition was addressed with additional validation. (CVE-2022-46689)

Note that Nessus has not tested for these issues but has instead relied only on the operating system's self-reported version number.

Solution

Upgrade to macOS 12.6.2 or later.
