Name of the Vulnerable Software and Affected Versions macOS versions prior to 10.12.2

Description The issue involves the xar component, which allows remote attackers to execute arbitrary code via a crafted archive that triggers the use of uninitialized memory locations. This is due to insufficient input validation in the xar component, allowing a remote attacker to exploit the issue and execute arbitrary code using a specially crafted archive.

Recommendations For macOS versions prior to 10.12.2, update to version 10.12.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the xar component until a patch is available.
