Vulnerability Note VU#200928

VLC Media Player format string vulnerability

Overview

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

I. Description

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.

II. Impact

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

III. Solution

Upgrade
VLC media player 0.8.6c has been released to address this issue.
Disable the affected components

Disabling the affected VLC plugins and components may mitigate this vulnerability. See the workarounds section of VideoLAN Security Advisory 0702 for more details.
