Multiple Browser Zero Width GIF Image Memory Corruption Vulnerability

Multiple web browsers are prone to memory corruption when handling GIF image files with a width field set to zero. Browsers reported to be affected are Netscape, Mozilla and Opera on Linux platforms. Other browsers and platforms may also be affected.

It may be possible to exploit this issue to cause a denial of service or potentially execute arbitrary code.

As multiple browsers are affected, this vulnerability may be due to a common issue in a library used to render GIF images (such as libungif). This possibility has not yet been confirmed.
