Gajim: Information disclosure — GLSA 201401-02

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

Affected Packages

net-im/gajim on all architectures
Affected versions < 0.15.3-r1
Unaffected versions >= 0.15.3-r1

Background

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

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"
