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.
