Security Advisory 0809
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
Details
When parsing the header of an invalid TY file, a stack-based buffer overflow might occur.
Impact
If successful, a malicious third party could trigger execution of arbitrary code within the context of the VLC media player.
Threat mitigation
Exploitation of this issue requires the user to explicitly open a specially crafted file.
Workarounds
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 (libty_plugin.*)
can be removed manually from the VLC plugin installation directory.
This will prevent opening of TiVo files.
Solution
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.
