Name of the Vulnerable Software and Affected Versions macOS versions prior to 10.12.5

Description The issue involves the WindowServer component and allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. This is due to a buffer overflow in the WindowServer component, which can be exploited by a remote attacker to achieve privilege escalation.

Recommendations For macOS versions prior to 10.12.5, update to version 10.12.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of the WindowServer component until a patch is available.
