Description

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

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
