Synopsis :

The remote Red Hat 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.
