Synopsis
========

Multiple vulnerabilities have been found in TagLib, possibly resulting
in Denial of Service.

Background
==========

TagLib is a library for reading and editing audio meta data.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/taglib            < 1.7.1                    >= 1.7.1

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

Multiple vulnerabilities have been found in TagLib:

* The "analyzeCurrent()" function in ape/apeproperties.cpp contains a
  division by zero error (CVE-2012-1107).
* The "parse()" function in inogg/xiphcomment.cpp contains an error
  when processing the "vendorLength" field (CVE-2012-1108).
* The "mid()" function in toolkit/tbytevector.cpp contains an integer
  overflow error (CVE-2012-1584).

Impact
======

A remote attacker could entice a user or automated system to open a
specially crafted OGG file with an application using TagLib, possibly
resulting in a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All TagLib users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/taglib-1.7.1"

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