Synopsis
========

Multiple vulnerabilities have been found in Gajim, the worst of which
may allow execution of arbitrary code.

Background
==========

Gajim is a Jabber and XMPP client written in PyGTK.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------

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

Multiple vulnerabilities have been discovered in Gajim. Please review
the CVE identifiers referenced below for details.

Impact
======

A remote attacker could entice a user to open a specially crafted link
using Gajim, possibly resulting in execution of arbitrary code with the
privileges of the process or a Denial of Service condition.
Furthermore, a remote attacker could use a specially crafted Jabber ID,
possibly resulting in execution of arbitrary SQL statements.

A local attacker could perform symlink attacks to overwrite arbitrary
files with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Gajim users should upgrade to the latest version:

  # emerge --sync
