Summary : Heap overflow in AVI demuxer Date : 12 July 2011 Affected versions : VLC media player 1.1.10 down to 0.5.0 ID : VideoLAN-SA-1106 CVE references : CVE-2011-2588
VLC media player suffers from a heap overflow vulnerability in the AVI file parser.
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 was unconfirmed.
Exploitation of those bugs requires the user to explicitly open specifically crafted malicious files.
The user may refrain from opening files from untrusted sources.
Alternatively, the AVI plugin (demux/libavi_plugin.*) can be removed. This will however prevent use of any of AVI media files.
VLC media player 1.1.11 addresses this issue and introduces further stability fixes. A source code patch is also available as an alternative.
This vulnerability was discovered by Hossein Lotfi and reported via Secunia.
