Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

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

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

      -------------------------------------------------------------------=

       Package          /   Vulnerable   /                    Unaffected
      -------------------------------------------------------------------=

    1  media-video/vlc      < 0.8.6i-r2                     >=3D 0.8.6i-r=
2

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All VLC users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=3Dmedia-video/vlc-0.8.6i-r2"
