Gentoo Linux Security Advisory
Title: Gajim: Information disclosure (GLSA 201401-02)
Severity: low
Exploitable: remote
Date: January 06, 2014
Bug(s): #442860
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: net-im/gajim
Vulnerable: < 0.15.3-r1
Unaffected: >= 0.15.3-r1
Architectures: 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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/gajim-0.15.3-r1"
|
