Synopsis

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

2.  Impact Information

Background

Banshee is a multimedia management and playback application for GNOME.

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Banshee users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # 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.
