Security Advisory 1104

Summary           : Integer overflow in XSPF playlist parser
Date              : 07 June 2011
Affected versions : VLC media player 1.1.9 down to 0.8.5
ID                : VideoLAN-SA-1104
CVE references    : CVE-2011-2194

Details

VLC media player suffers from an integer overflow vulnerability in the XSPF playlist file parser.

Impact

If successful, a malicious third party could crash the player instance. Arbitrary code execution within the context of VLC media player might be possible, though it seems impractical.

Threat mitigation

Exploitation of those bugs requires the user to explicitly open specifically crafted malicious files.

Workarounds

The user may refrain from opening files from untrusted sources.

Alternatively, the playlist plugin (demux/libplaylist_plugin.*) can be removed. This will however prevent use of any of all supported playlist file formats.

Solution

VLC media player 1.1.10 addresses this issue and introduces further stability fixes.
