Apple Mac OS X CoreText contains an uninitialized pointer vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.


Apple Mac OS X CoreText is a framework for handling text on Mac OS X Tiger (10.4) and later. Mac OS X CoreText fails to properly initialize pointers, which can cause memory corruption. Any application that uses the CoreText framework for handling text may be vulnerable.


By convincing a user to view specially crafted text, a remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial of service on a vulnerable system.
