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. (CVE-2013-4566) Red Hat would like to thank Albert Smith of OUSD(AT&amp 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.
