Summary : Buffer overflow in VLC TiVo demuxer Date : October 2008 Affected versions : VLC media player 0.9.4 down to 0.9.0 ID : VideoLAN-SA-0809 CVE reference : CVE-2008-4654, CVE-2008-4686
When parsing the header of an invalid TY file, a stack-based buffer overflow might occur.
If successful, a malicious third party could trigger execution of arbitrary code within the context of the VLC 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 TY demux plugin (
can be removed manually from the VLC plugin installation directory.
This will prevent opening of TiVo files.
VLC media player 0.9.5 addresses this issue. Patches for older versions are available from the official VLC source code repository 0.9-bugfix branch.
