Synopsis
========

Multiple buffer overflow vulnerabilities in libmikmod may allow an
attacker to execute arbitrary code or cause a Denial of Service
condition.

Background
==========

libmikmod is a library to play a wide range of module formats.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/libmikmod     < 3.2.0_beta2-r3      >= 3.2.0_beta2-r3
                                                        *>= 3.1.12-r1

Description
===========

Multiple boundary errors have been found in load_it.c in libmikmod,
which may cause a buffer overflow.

Impact
======

A remote attacker could entice a user to open specially crafted files
in an application linked against libmikmod, possibly resulting in
execution of arbitrary code with the permissions of the user running
the application, or Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libmikmod 3.2 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=media-libs/libmikmod-3.2.0_beta2-r3"

All libmikmod 3.1 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/libmikmod-3.1.12-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
