Synopsis
========
Multiple vulnerabilities in ModPlug could result in execution of
arbitrary code or Denial of Service.

Background
==========
ModPlug is a library for playing MOD-like music.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libmodplug < 0.8.8.4 >= 0.8.8.4

Description
===========
Multiple vulnerabilities have been found in ModPlug:

* The ReadS3M method in load_s3m.cpp fails to validate user-supplied
information, which could cause a stack-based buffer overflow
(CVE-2011-1574).
* The "CSoundFile::ReadWav()" function in load_wav.cpp contains an
integer overflow which could cause a heap-based buffer overflow
(CVE-2011-2911).
* The "CSoundFile::ReadS3M()" function in load_s3m.cpp contains
multiple boundary errors which could cause a stack-based buffer
overflow (CVE-2011-2912).
* The "CSoundFile::ReadAMS()" function in load_ams.cpp contains an
off-by-one error which could cause memory corruption (CVE-2011-2913).
* The "CSoundFile::ReadDSM()" function in load_dms.cpp contains an
off-by-one error which could cause memory corruption (CVE-2011-2914).
* The "CSoundFile::ReadAMS2()" function in load_ams.cpp contains an
off-by-one error which could cause memory corruption (CVE-2011-2915).

Impact
======
A remote attacker could entice a user to open a specially crafted media
file, possibly resulting in execution of arbitrary code, or a Denial of
Service condition.

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-0.8.8.4"

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since August 27, 2011. It is likely that your system is
already no longer affected by this issue.
