Subject: CVE request: libmodplug: multiple vulnerabilities reported in <= 0.8.8.3

Hi ppl,

from RH bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=728371

The 2nd issue seems to be CVE-2011-1574 other seem to be untracked.

A number of vulnerabilities were reported in libmodplug, which can be exploited
to cause a DoS or possibly compromise an application using the library [1]:

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.

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.

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.

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.

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.

Upstream patches are available to correct the flaws [2],[3],[4],[5]

While older gstreamer-plugins contains an embedded copy of libmodplug, it is
not yet known to what extent it is affected by these flaws.
