Synopsis
========

An environment variable processing error has been reported in Banshee,
possibly allowing local attacker to load a specially crafted shared
library.

Background
==========

Banshee is a multimedia management and playback application for GNOME.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-sound/banshee         < 1.8.0-r1               >= 1.8.0-r1

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

Banshee places a zero-length directory name in PATH, which allows
libraries to be loaded from the working directory.

Impact
======

A local attacker could put specially crafted library into working
directory of Banshee, 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 Banshee users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-sound/banshee-1.8.0-r1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since November 17, 2010. It is likely that your system is
already no longer affected by this issue.
