Synopsis
========

ModPlug contains several buffer overflows that could lead to the
execution of arbitrary code.

Background
==========

ModPlug is a library for playing MOD-like music.

Affected packages
=================

    -------------------------------------------------------------------
     Package                     /  Vulnerable  /           Unaffected
    -------------------------------------------------------------------
  1  media-libs/libmodplug            < 0.8.7                 >= 0.8.7
  2  media-libs/gst-plugins-bad      < 0.10.11              >= 0.10.11
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

Two vulnerabilities have been reported in ModPlug:

* dummy reported an integer overflow in the CSoundFile::ReadMed()
  function when processing a MED file with a crafted song comment or
  song name, which triggers a heap-based buffer overflow
  (CVE-2009-1438).

* Manfred Tremmel and Stanislav Brabec reported a buffer overflow in
  the PATinst() function when processing a long instrument name
  (CVE-2009-1513).

The GStreamer Bad plug-ins (gst-plugins-bad) before 0.10.11 built a
vulnerable copy of ModPlug.

Impact
======

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

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All ModPlug users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/libmodplug-0.8.7"

gst-plugins-bad 0.10.11 and later versions do not include the ModPlug
plug-in (it has been moved to media-plugins/gst-plugins-modplug). All
gst-plugins-bad users should upgrade to the latest version and install
media-plugins/gst-plugins-modplug:

    # emerge --sync
    # emerge --ask --oneshot -v ">=media-libs/gst-plugins-bad-0.10.11"
    # emerge --ask --verbose "media-plugins/gst-plugins-modplug"
