"The remote host is using Winamp, a popular media player for Windows.

The version of Winamp installed on the remote Windows host has a
buffer overflow that may allow an attacker to execute arbitrary code
on the remote host subject to the privileges of the user running
Winamp.

To exploit this, an attacker would have to send a malformed playlist
(.m3u) to a user of this host and trick him into loading it with the
application.");
