Fedora 19 : mod_nss-1.0.8-27.fc19 (2013-22787)
medium Nessus Plugin ID 71384

Synopsis
The remote Fedora host is missing a security update.Description
A flaw was found in the way NSSVerifyClient was handled when used in both server / vhost context as well as directory context (specified either via <Directory> or <Location> directive). If 'NSSVerifyClient none' was set in the server / vhost context (i.e. when server is configured to not request or require client certificate authentication on the initial connection), and client certificate authentication was expected to be required for a specific directory via 'NSSVerifyClient require' setting, mod_nss failed to properly require expected certificate authentication. Remote attacker able to connect to the web server using such mod_nss configuration and without a valid client certificate could possibly use this flaw to access content of the restricted directories.Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected mod_nss package.See Also
