Name of the Vulnerable Software and Affected Versions iOS versions prior to 10.3 macOS versions prior to 10.12.4 tvOS versions prior to 10.2 watchOS versions prior to 3.2

Description The issue involves the FontParser component and allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted font file. This is due to a buffer overflow in memory, which can be exploited by a remote attacker to achieve the aforementioned outcomes.

Recommendations For iOS versions prior to 10.3, update to version 10.3 or later. For macOS versions prior to 10.12.4, update to version 10.12.4 or later. For tvOS versions prior to 10.2, update to version 10.2 or later. For watchOS versions prior to 3.2, update to version 3.2 or later. As a temporary workaround, consider disabling the FontParser component until a patch is available.
