Winamp Playlist Buffer Overflow

   Original release date: February 1, 2006
   Last revised: --
   Source: US-CERT


Systems Affected

   Microsoft Windows systems with Winamp 5.12 or earlier


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.
