Description

Drew Yao of Apple Product Security reported a vulnerability in Mozilla graphics code which handles GIF rendering in Mac OS X. He demonstrated that a GIF file could be specially crafted to cause the browser to free an uninitialized pointer. An attacker could use this vulnerability to crash the browser and potentially execute arbitrary code on the victim's computer.

Firefox 2 is not affected by this issue.
