The remote Fedora host is missing a security update.
This update includes the latest stable release of the Apache HTTP Server, version 2.2.21. Two security issues have been fixed : mod_proxy_ajp when combined with mod_proxy_balancer: Prevents unrecognized HTTP methods from marking ajp: balancer members in an error state, avoiding denial of service. (CVE-2011-3348) Fixes to the handling of byte-range requests to use less memory, to avoid denial of service. (CVE-2011-3192) A number of bugs have been fixed as well. See : http://www.apache.org/dist/httpd/CHANGES_2.2.21 http://www.apache.org/dist/httpd/CHANGES_2.2.20 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.
