Vulnerability Note VU#200928

VLC Media Player format string vulnerability

Original Release date: 23 Jul 2007 | Last revised: 24 Jul 2007


VLC contains a format string vulnerability that may allow an attacker to execute code.


VideoLAN (VLC) is a streaming media player that runs on multiple platforms.

From VideoLAN Security Advisory 0702:

    VLC media player Ogg/Vorbis, Ogg/Theora, CDDA (CD Digital Audio) and SAP (Service Announce Protocol) plugins are prone to a C-style format string vulnerability when trying to parse a media data stream.

    Valid but carefully crafted .ogg (Vorbis) or .ogm (Theora) files, CDDB entries or SAP/SDP messages can trigger the bug. We therefore consider this bug to have a high severity.

Note that VLC distributes a plugin for Mozilla-based browsers. If the VLC browser plugin is used, an attacker may be able to exploit this vulnerability by convincing a user to go to a webpage.


A remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user running VLC.


VLC media player 0.8.6c has been released to address this issue.
