The remote host is missing an update to httpd
announced via advisory FEDORA-2009-8812.
The Apache HTTP Server is a powerful, efficient, and extensible
web server.
Update Information:
This update includes the latest release of the Apache HTTP Server, version
2.2.13, fixing several security issues:
* Fix a potential Denial-of-Service attack against mod_deflate or
other modules, by forcing the server to consume CPU time in compressing
a large file after a client disconnects. (CVE-2009-1891)
* Prevent the Includes Option from being enabled in an
.htaccess file if the AllowOverride restrictions do not permit it.
(CVE-2009-1195)
* Fix a potential Denial-of-Service attack against mod_proxy
in a reverse proxy configuration, where a remote attacker can force a proxy
process to consume CPU time indefinitely. (CVE-2009-1890)
* mod_proxy_ajp: Avoid delivering content from a previous request
which failed to send a request body. (CVE-2009-1191)
Many bug fixes are also included
see the upstream
changelog for further details:
