   An update that fixes 6 vulnerabilities is now available. It
   includes one version update.

Description:

   This update of libmodplug0 fixes the following issues:

   1) An integer overflow error exists within the
   "CSoundFile::ReadWav()" function (src/load_wav.cpp) when
   processing certain WAV files. This can be exploited to
   cause a heap-based buffer overflow by tricking a user into
   opening a specially crafted WAV file. (CVE-2011-2911)

   2) Boundary errors within the "CSoundFile::ReadS3M()"
   function (src/load_s3m.cpp) when processing S3M files can
   be exploited to cause stack-based buffer overflows by
   tricking a user into opening a specially crafted S3M file.
   (CVE-2011-2912)


   3) An off-by-one error within the "CSoundFile::ReadAMS()"
   function (src/load_ams.cpp) can be exploited to cause a
   stack corruption by tricking a user into opening a
   specially crafted AMS file. (CVE-2011-2913)

   4) An off-by-one error within the "CSoundFile::ReadDSM()"
   function (src/load_dms.cpp) can be exploited to cause a
   memory corruption by tricking a user into opening a
   specially crafted DSM file. (CVE-2011-2914)

   5) An off-by-one error within the "CSoundFile::ReadAMS2()"
   function (src/load_ams.cpp) can be exploited to cause a
   memory corruption by tricking a user into opening a
   specially crafted AMS file. (CVE-2011-2915)

   Also an overflow in the ABC loader was fixed.
   (CVE-2011-1761)
