"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."
