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"
| OS | Version | Architecture | Package | Version | Filename |
|---|---|---|---|---|---|
| Gentoo | any | all | net-im/gajim | < 0.15.3-r1 | UNKNOWN |
