RHEL 5 / 6 : mod_nss (RHSA-2013:1779)

This script is Copyright (C) 2013-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated mod_nss package that fixes one security issue is now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

The mod_nss module provides strong cryptography for the Apache HTTP
Server via the Secure Sockets Layer (SSL) and Transport Layer Security
(TLS) protocols, using the Network Security Services (NSS) security

A flaw was found in the way mod_nss handled the NSSVerifyClient
setting for the per-directory context. When configured to not require
a client certificate for the initial connection and only require it
for a specific directory, mod_nss failed to enforce this requirement
and allowed a client to access the directory when no valid client
certificate was provided. (CVE-2013-4566)

Red Hat would like to thank Albert Smith of OUSD(AT&L) for reporting
this issue.

All mod_nss users should upgrade to this updated package, which
contains a backported patch to correct this issue. The httpd service
must be restarted for this update to take effect.
