ModPlug: User-assisted execution of arbitrary code — GLSA 200907-07

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

Affected packages

media-libs/libmodplug on all architectures
Affected versions < 0.8.7
Unaffected versions >= 0.8.7
media-libs/gst-plugins-bad on all architectures
Affected versions < 0.10.11
Unaffected versions >= 0.10.11


ModPlug is a library for playing MOD-like music.


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.


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.


There is no known workaround at this time.


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