Synopsis
=======
A buffer overflow vulnerability has been discovered in libsndfile.

Background
=========
libsndfile is a library for reading and writing various formats of
audio files including WAV and FLAC.

Affected packages
================
    -------------------------------------------------------------------
     Package                /   Vulnerable   /              Unaffected
    -------------------------------------------------------------------
  1  media-libs/libsndfile      < 1.0.17-r1               >= 1.0.17-r1

Description
==========
Robert Buchholz of the Gentoo Security team discovered that the
flac_buffer_copy() function does not correctly handle FLAC streams with
variable block sizes which leads to a heap-based buffer overflow
(CVE-2007-4974).

Impact
=====
A remote attacker could exploit this vulnerability by enticing a user
to open a specially crafted FLAC file or network stream with an
application using libsndfile. This might lead to the execution of
arbitrary code with privileges of the user playing the file.

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-1.0.17-r1"
