Summary : Heap corruption in CDG decoder Date : January 2011 Affected versions : VLC media player 1.1.5 and earlier ID : VideoLAN-SA-1101 CVE reference : CVE-2011-0021
When parsing an invalid CDG file, insufficient boundary checks might lead to corruption of the heap.
If successful, it is unknown whether a malicious third party might be able to trigger execution of arbitrary code. Successful exploitation of this bug can crash the process of the media player.
Exploitation of this issue requires the user to explicitly open a specially crafted file.
The user should refrain from opening files from untrusted third parties or accessing untrusted remote sites (or disable the VLC browser plugins), until the patch is applied.
Alternatively, the CDG decoder plugin
can be removed manually from the VLC plugin installation directory.
VLC media player 1.1.6 addresses this issue. Patches for older versions are available from the official VLC source code repositories.
