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

The vulnerability is caused due to an integer overflow error within
the "Open()" function in modules/demux/tta.c. This can be exploited
to cause a heap-based buffer overflow via specially crafted TTA
data.

Successful exploitation may potentially allow execution of arbitrary
code.

The vulnerability is confirmed in version 0.8.6i. Other versions may
also be affected.

SOLUTION:
Do not open untrusted files using VLC Media Player.
