Summary : Heap corruption in MP4 demultiplexer Date : April 2011 Affected versions : VLC media player 1.1.8 down to 1.0.0 ID : VideoLAN-SA-1103 CVE reference : CVE-2011-1684
When parsing some MP4 (MPEG-4 Part 14) files, insufficient buffer size 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 an MP4 file with some specific content.
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 MP4 decoder plugin
can be removed manually from the VLC plugin installation directory.
VLC media player 1.1.9 will address this issue. Patches for older versions are available from the official VLC source code repositories.
