RHSA-2007:0532 - Security Advisory

Topic

Updated Apache httpd packages that correct two security issues are now
available for Red Hat Enterprise Linux 2.1.

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

Description

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 who has 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)

A flaw was found in the Apache HTTP Server mod_status module. Sites with
the server-status page publicly accessible and ExtendedStatus enabled were
vulnerable 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. (CVE-2006-5752)

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