CentOS Errata and Security Advisory CESA-2007:0662
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).
Users of httpd should upgrade to these updated packages, which contain backported patches to correct this issue. Users should restart Apache after installing this update.
