GLSA 201401-02: Gajim: Information disclosure

Severity:low
Title:Gajim: Information disclosure
Date:01/06/2014
Bugs: #442860
ID:201401-02

Synopsis

An error in Gajim causes invalid OpenSSL certificates to be accepted as valid.

Background

Gajim is a Jabber/XMPP client which uses GTK+.

Affected packages

Package Vulnerable Unaffected Architecture(s)
net-im/gajim < 0.15.3-r1 >= 0.15.3-r1 All supported architectures

Description

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.

Impact

A remote attacker might employ a specially crafted certificate to conduct man-in-the-middle attacks on SSL connections and potentially disclose sensitive information.

Workaround

There is no known workaround at this time.

Resolution

All Gajim users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-im/gajim-0.15.3-r1"
