"The remote host is affected by the vulnerability described in GLSA-200907-07
(ModPlug: User-assisted execution of arbitrary code)

    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."
