"The 3ivx MPEG-4 compression suite is installed on the remote host. It
contains an MP4 codec for use with media players such as Windows Media
Player for creating and playing back MPEG-4 / MP4 files.

The version of this codec on the remote host is affected by a buffer
overflow vulnerability. If an attacker can trick a user on the
affected host into opening a specially crafted MP4 file with a media
player that uses this codec, this issue could be leveraged to execute
arbitrary code on the affected host subject to the user's privileges.");
