critical Nessus Plugin ID 168670

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 11.x prior to 11.7.2. It is, therefore, affected by multiple vulnerabilities:

 - The issue was addressed with improved memory handling. This issue is fixed in tvOS 16.2, macOS Monterey 12.6.2, macOS Ventura 13.1, macOS Big Sur 11.7.2, iOS 16.2 and iPadOS 16.2, watchOS 9.2. A remote user may be able to cause kernel code execution. (CVE-2022-42842)

 - The issue was addressed with improved memory handling. This issue is fixed in macOS Monterey 12.6.2, macOS Ventura 13.1, macOS Big Sur 11.7.2. An app may be able to execute arbitrary code with kernel privileges.
 (CVE-2022-32942)

 - 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)

 - A logic issue was addressed with improved checks. This issue is fixed in macOS Monterey 12.6.2, macOS Big Sur 11.7.2, macOS Ventura 13. An app may bypass Gatekeeper checks. (CVE-2022-42821)

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 11.7.2 or later.
