Category:Red Hat Local Security Checks
Title:RedHat Update for mod_nss RHSA-2013:1779-01
Summary:The remote host is missing an update for the 'mod_nss'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'mod_nss'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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 library.

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.

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

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.

Affected Software/OS:
mod_nss on Red Hat Enterprise Linux (v. 5 server),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Please Install the Updated Packages.
