| Severity: | low |
| Title: | Gajim: Information disclosure |
| Date: | 01/06/2014 |
| Bugs: | |
| 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"
