Summary : Buffer overflow in Real demuxer Date : November 2008 Affected versions : VLC media player 0.9.8 down to 0.9.0 ID : VideoLAN-SA-0811 CVE reference : CVE-2008-5276
When parsing the header of an invalid Real Media file an integer overflow might occur then trigger a heap-based buffer overflow.
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 Real demuxer plugin
can be removed manually from the VLC plugin installation directory.
VLC media player 0.9.8a addresses this issue. Patches for older versions are available from the official VLC source code repository 0.9-bugfix branch.
