Synopsis
========
Two vulnerabilities in VLC may lead to the remote execution of
arbitrary code.

Background
==========
VLC is a cross-platform media player and streaming server.

Affected packages
=================
-------------------------------------------------------------------=
Package / Vulnerable / Unaffected
-------------------------------------------------------------------=
1 media-video/vlc < 0.8.6i-r2 >= 0.8.6i-r=2

Description
===========
g_ reported the following vulnerabilities:

* An integer overflow leading to a heap-based buffer overflow in the
Open() function in modules/demux/tta.c (CVE-2008-3732).

* A signedness error leading to a stack-based buffer overflow in the
mms_ReceiveCommand() function in modules/access/mms/mmstu.c
(CVE-2008-3794).

Impact
======
A remote attacker could entice a user to open a specially crafted file,
possibly resulting in the remote execution of arbitrary code with the
privileges of the user running the application.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All VLC users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/vlc-0.8.6i-r2"
