Summary : Buffer overflow in Real demuxer Date : December 2010 Affected versions : VLC media player 1.1.5 and earlier ID : VideoLAN-SA-1007 CVE reference : CVE-2010-3907
When parsing the header of an invalid Real Media file an integer overflow might occur then trigger a heap-based buffer overflow.
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 Real demuxer 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.
