Vulnerability Assessment Details
Check for the version of the httpd packages
Detailed Explanation for this Vulnerability Assessment
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, a possible hacker 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, a possible hacker could send carefully crafted requests in order to
consume resources, potentially leading to a Denial of Service.
Users of Apache httpd should update to these errata packages that contain
backported patches to correct these issues.
