Synopsis
========

A vulnerability in Nagstamon could expose user credentials to a remote
attacker.

Background
==========

Nagstamon is a Nagios status monitor application.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/nagstamon >= 0.9.11_rc1 >= 0.9.11_rc1

Title: Gajim: Information disclosure
Date: January 06, 2014
Bugs: #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 / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-im/gajim < 0.15.3-r1 >= 0.15.3-r1

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"
