Scientific Linux Security Update : mod_nss on SL5.x, SL6.x i386/x86_64

Medium Nessus Plugin ID 71304


The remote Scientific Linux host is missing one or more security updates.


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)

The httpd service must be restarted for this update to take effect.


Update the affected mod_nss and / or mod_nss-debuginfo packages.
