Fedora 15 : httpd-2.2.21-1.fc15 (2011-12715)

high Nessus Plugin ID 56217
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.


Update the affected httpd package.
