Synopsis
========

A vulnerability has been found in GNOME Autoar that could allow a
remote attacker to execute arbitrary code.

Background
==========

GNOME Autoar provides functions and widgets for GNOME applications
which want to use archives as a method to transfer directories over the
internet.

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

     -------------------------------------------------------------------
      Package              /     Vulnerable     /            Unaffected
     -------------------------------------------------------------------
   1  app-arch/gnome-autoar        < 0.3.1                    >= 0.3.1

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

It was discovered that GNOME Autoar could extract files outside of the
intended directory.

Impact
======

A remote attacker could entice a user to open a specially crafted
archive using GNOME Autoar, 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 GNOME Autoar users should upgrade to the latest version:

   # emerge --sync
   # emerge --ask --oneshot --verbose ">=app-arch/gnome-autoar-0.3.1"
