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.
