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.
