Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: 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&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. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5.
