The version of Winamp installed on the remote Windows host contains a
plug-in to handle playing FLAC files that contains several integer
buffer overflow vulnerabilities. If an attacker can trick a user on
the affected host into opening a specially crafted FLAC file, he may
be able to leverage this issue to execute arbitrary code on the host
subject to the user's privileges.");
