Summary

The Apache HTTP Server is a popular Web server.
A flaw was found in the mod_proxy Apache module. An attacker in control of a Web server to which requests were being proxied could have caused a limited denial of service due to CPU consumption and stack exhaustion. (CVE-2008-2364)
A flaw was found in the mod_proxy_ftp Apache module. If Apache was configured to support FTP-over-HTTP proxying, a remote attacker could have performed a cross-site scripting attack. (CVE-2008-2939)
In addition, these updated packages fix a bug found in the handling of the "ProxyRemoteMatch" directive in the Red Hat Enterprise Linux 4 httpd packages. This bug is not present in the Red Hat Enterprise Linux 3 or Red Hat Enterprise Linux 5 packages.
Users of httpd should upgrade to these updated packages, which contain backported patches to correct these issues.
