Synopsis
=======
An integer overflow in libsndfile might allow remote attackers to
execute arbitrary code or cause a Denial of Service condition.

Background
=========
Libsndfile is a C library for reading and writing files containing
sampled sound through one standard library interface.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/libsndfile        < 1.0.25                  >= 1.0.25

Description
==========
An integer overflow flaw has been discovered in Libsndfile.

Impact
=====
A remote attacker could entice a user to open a specially crafted PAF
file using libsndfile, possibly resulting in execution of arbitrary
code with the privileges of the process, or a Denial of Service
condition.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All libsndfile users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.25"

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

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since September 12, 2011. It is likely that your system is
already no longer affected by this issue.
