CentOS 3 / 4 : httpd (CESA-2005:608)

critical Nessus Plugin ID 21845

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated Apache httpd packages that correct two security issues are now available for Red Hat Enterprise Linux 3 and 4.

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

The Apache HTTP Server is a popular and freely-available Web server.

A flaw was discovered in mod_ssl's handling of the 'SSLVerifyClient' directive. This flaw occurs if a virtual host is configured using 'SSLVerifyClient optional' and a directive 'SSLVerifyClient required' is set for a specific location. For servers configured in this fashion, an attacker may be able to access resources that should otherwise be protected, by not supplying a client certificate when connecting. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2700 to this issue.

A flaw was discovered in Apache httpd where the byterange filter would buffer certain responses into memory. If a server has a dynamic resource such as a CGI script or PHP script that generates a large amount of data, an attacker could send carefully crafted requests in order to consume resources, potentially leading to a Denial of Service. (CVE-2005-2728)

Users of Apache httpd should update to these errata packages that contain backported patches to correct these issues.

Solution

Update the affected httpd packages.
