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"
