httpd, mod_ssl security update

CentOS Errata and Security Advisory CESA-2009:1148

The Apache HTTP Server is a popular Web server.

A denial of service flaw was found in the Apache mod_proxy module when it
was used as a reverse proxy. A remote attacker could use this flaw to force
a proxy process to consume large amounts of CPU time. (CVE-2009-1890)

A denial of service flaw was found in the Apache mod_deflate module. This
module continued to compress large files until compression was complete,
even if the network connection that requested the content was closed before
compression completed. This would cause mod_deflate to consume large
amounts of CPU if mod_deflate was enabled for a large file. (CVE-2009-1891)

All httpd users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the httpd daemon must be restarted for the update to take effect.
