3. Problem description:
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.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/):
167102 - CAN-2005-2728 byterange memory DoS
167194 - CAN-2005-2700 SSLVerifyClient flaw
