<package name="net-im/gajim" auto="yes" arch="*">

<background>
<p>Gajim is a Jabber/XMPP client which uses GTK+.</p>
</background>
<description>
<p>The _ssl_verify_callback() function in tls_nb.py does not properly
validate SSL certificates, causing any certificate to be accepted as
valid as long as the root CA is valid.
</p>
</description>
<impact type="low">
<p>A remote attacker might employ a specially crafted certificate to
conduct man-in-the-middle attacks on SSL connections and potentially
disclose sensitive information.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Gajim users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/gajim-0.15.3-r1"
</code>
</resolution>
