The remote host is vulnerable to a buffer overflow.
The remote host is using a version of MPlayer, a multimedia video and audio application. This version of MPlayer is vulnerable to a buffer overflow due to a lack of content parsing. An attacker exploiting this flaw would need to craft a malicious media file and then convince a local user to download and play the file within MPlayer. Successful exploitation would result in arbitrary code being executed locally.
Upgrade to version 1.0pre8 or higher.
