Apple Mac OS X CFNetwork HTTP Header Handling Heap Buffer Overflow Vulnerability

Apple Mac OS X is prone to a heap-based buffer-overflow vulnerability in the CFNetwork component.

An attacker can exploit this issue by tricking a victim into visiting a specially crafted website.

A successful attack will allow attacker-supplied code to run in the context of the user running the affected application.
