An error in Gajim causes invalid OpenSSL certificates to be accepted as valid.
| Package | net-im/gajim on all architectures |
|---|---|
| Affected versions | < 0.15.3-r1 |
| Unaffected versions | >= 0.15.3-r1 |
Gajim is a Jabber/XMPP client which uses GTK+.
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.
A remote attacker might employ a specially crafted certificate to conduct man-in-the-middle attacks on SSL connections and potentially disclose sensitive information.
There is no known workaround at this time.
All Gajim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/gajim-0.15.3-r1"
