RHEL 5 : httpd (RHSA-2007:0556)

Medium Nessus Plugin ID 25610


The remote Red Hat host is missing one or more security updates.


Updated Apache httpd packages that correct three security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The Apache HTTP Server is a popular Web server.

The Apache HTTP Server did not verify that a process was an Apache child process before sending it signals. A local attacker with the ability to run scripts on the Apache HTTP Server could manipulate the scoreboard and cause arbitrary processes to be terminated which could lead to a denial of service (CVE-2007-3304). This issue is not exploitable on Red Hat Enterprise Linux 5 if using the default SELinux targeted policy.

A flaw was found in the Apache HTTP Server mod_status module. On sites where the server-status page is publicly accessible and ExtendedStatus is enabled this could lead to a cross-site scripting attack. On Red Hat Enterprise Linux the server-status page is not enabled by default and it is best practice to not make this publicly available.

A bug was found in the Apache HTTP Server mod_cache module. On sites where caching is enabled, a remote attacker could send a carefully crafted request that would cause the Apache child process handling that request to crash. This could lead to a denial of service if using a threaded Multi-Processing Module. (CVE-2007-1863)

Users of httpd should upgrade to these updated packages, which contain backported patches to correct these issues. Users should restart Apache after installing this update.
