Security Advisory 1302

Summary           : Buffer Overflow in ASF Demuxer
Date              : January 2013
Affected versions : VLC media player 2.0.5 and earlier
ID                : VideoLAN-SA-1302
CVE reference     : CVE-XXXX-XXXX

Details

When parsing a specially crafted ASF movie, a buffer overflow might occur.

Impact

If successful, a malicious third party could trigger an invalid memory access, 
leading to a crash of VLC media player's process. In some cases attackers might 
exploit this issue to execute arbitrary code within the context of the 
application but this information is not confirmed.

Threat mitigation

Exploitation of this issue requires the user to explicitly open a specially 
crafted ASF movie.

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 ASF demuxer (libasf_plugin.*) can be removed manually from 
the VLC plugin installation directory. This will prevent ASF movie playback.

Solution

This issue is addressed in VLC media player 2.0.x source code repository by 
replacing a macro with a static inline and improved bounds checking.

This patch is included in VLC's future 2.0.6 release.

Windows and Mac OS X builds can be found on the VideoLAN nightlies website.
