Source: US-CERT

Systems Affected

Overview

America Online has released Winamp 5.13 to correct a buffer overflow
vulnerability. Exploitation of this vulnerability could allow a remote
attacker to execute arbitrary code with the privileges of the user.

I. Description

Winamp is a media player that is commonly used to play MP3 files.
Winamp 5.13 resolves a buffer overflow vulnerability in how playlist
files are handled. Details are available in the following
Vulnerability Note:

VU#604745 - Winamp fails to properly handle playlists with long
computer names

Winamp contains a buffer overflow vulnerability when processing a
playlist that specifies a long computer name. This may allow a remote
unauthenticated attacker to execute arbitrary code on a vulnerable
system.

II. Impact

By convincing a user to open a specially crafted playlist file, a
remote unauthenticated attacker may be able to execute arbitrary code
with the privileges of the user. Winamp may open a playlist file
without any user interaction as the result of viewing a web page or
other HTML document.

III. Solution

Upgrade

Upgrade to Winamp 5.13.
