Synopsis
========

SoX contains two buffer overflow vulnerabilities in the WAV header
parser code.

Background
==========

SoX is a command line utility that can convert various formats of
computer audio files in to other formats.

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

    -------------------------------------------------------------------
     Package          /    Vulnerable    /                  Unaffected
    -------------------------------------------------------------------
  1  media-sound/sox      <= 12.17.4-r1                  >= 12.17.4-r2

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

Ulf Harnhammar discovered two buffer overflows in the sox and play
commands when handling WAV files with specially crafted header fields.

Impact
======

By enticing a user to play or convert a specially crafted WAV file an
attacker could execute arbitrary code with the permissions of the user
running SoX.

Workaround
==========

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of SoX.

Resolution
==========

All SoX users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=media-sound/sox-12.17.4-r2"
    # emerge ">=media-sound/sox-12.17.4-r2"
