Gentoo Linux Security Advisory

Title: ModPlug: User-assisted execution of arbitrary code (GLSA 201203-16)
Severity: normal
Exploitable: remote
Date: March 16, 2012
Bug(s): #362503, #379557
ID: 201203-16

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: media-libs/libmodplug
Vulnerable: < 0.8.8.4
Unaffected: >= 0.8.8.4
Architectures: All supported architectures


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:
Code:
# 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.
