3. Problem description:

The Apache HTTP Server is a powerful, full-featured, efficient, and
freely-available Web server.

Watchfire reported a flaw that occured when using the Apache server as an
HTTP proxy.  A remote attacker could send an HTTP request with both a
"Transfer-Encoding: chunked" header and a "Content-Length" header.  This
caused Apache to incorrectly handle and forward the body of the request in
a way that the receiving server processes it as a separate HTTP request.
This could allow the bypass of Web application firewall protection or lead
to cross-site scripting (XSS) attacks.  The Common Vulnerabilities and
Exposures project (cve.mitre.org) assigned the name CAN-2005-2088 to this
issue.

Marc Stern reported an off-by-one overflow in the mod_ssl CRL verification
callback.  In order to exploit this issue the Apache server would need to
be configured to use a malicious certificate revocation list (CRL).   The
Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the
name CAN-2005-1268 to this issue.

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/):

161893 - Bug 145666 is missing a ',' after REDIRECT_REMOTE_USER
162244 - CAN-2005-2088 httpd proxy request smuggling
163013 - CAN-2005-1268 mod_ssl off-by-one
