Synopsis
========

Multiple heap overflows in SoX may allow remote attackers to execute
arbitrary 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              < 14.4.2                  >= 14.4.2

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

A heap-based buffer overflow can be triggered when processing a
malicious NIST Sphere or WAV audio file.

Impact
======

A remote attacker could coerce the victim to run SoX against their
malicious file. This may be leveraged by an attacker to gain control of
program execution with the privileges of the user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All SoX users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-sound/sox-14.4.2"
