DESCRIPTION:
A vulnerability has been reported in VLC Media Player, which can
potentially be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error within the MP4
demuxer (modules/demux/mp4/mp4.c). This can be exploited to overwrite
an almost arbitrary memory address via a specially crafted MPEG-4
file.     

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in version 0.8.6d. Other versions may
also be affected.

SOLUTION:
Apply vendor patch.

the vulnerability.
