Impact low

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

2.  Impact Information


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


The _ssl_verify_callback() function in does not properly validate SSL certificates, causing any certificate to be accepted as valid as long as the root CA is valid.


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

3.  Resolution Information


There is no known workaround at this time.


All Gajim users should upgrade to the latest version:

Code Listing 3.1: Resolution

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