    Date: September 07, 2008
    Bugs: #235238, #235589
      ID: 200809-06

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-r2

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"
