Discussion

Apple Mac OS X Compact Font Format (CFF) Heap Based Buffer Overflow Vulnerability

Apple Mac OS X is prone to a heap-based buffer-overflow vulnerability that affects the Apple Type Services component when handling Compact Font Format (CFF) fonts.

An attacker can exploit this issue to execute arbitrary code in the context of the application using the component. Failed exploit attempts will cause a denial-of-service condition.

NOTE: This issue was previously covered in BID 34926 (Apple Mac OS X 2009-002 Multiple Security Vulnerabilities), but has been assigned its own record to better document it.
