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
CAN-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. (CAN-2005-2728)
Users of Apache httpd should update to these errata packages that contain
backported patches to correct these issues.
