Extended Description

The Microsoft Windows Media Player plugin for non-Microsoft browsers is prone to a buffer-overflow vulnerability. The application fails to do proper boundary checks on user-supplied data before using it in a finite-sized buffer. An attacker can exploit this issue to execute arbitrary code on the victim user's computer in the context of the victim user. This may facilitate a compromise of the affected computer. This issue is exploitable only through non-Microsoft browsers that have the Media Player plugin installed. Possible browsers include Firefox .9 and later and Netscape 8; other browsers with the plugin installed may also be affected.
