[RHSA-2010:0396-01] Moderate: httpd and httpd22 security and enhancement update



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

=====================================================================
                   Red Hat Security Advisory

Synopsis:          Moderate: httpd and httpd22 security and enhancement update
Advisory ID:       RHSA-2010:0396-01
Product:           JBoss Enterprise Web Server
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0396.html
Issue date:        2010-05-05
CVE Names:         CVE-2010-0408 CVE-2010-0434 
=====================================================================

1. Summary:

Updated httpd and httpd22 packages that fix two security issues and add one
enhancement are now available for JBoss Enterprise Web Server 1.0.1 for Red
Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

JBoss Enterprise Web Server 1.0 for RHEL 4 AS - i386, x86_64
JBoss Enterprise Web Server 1.0 for RHEL 4 ES - i386, x86_64
JBoss Enterprise Web Server 1.0 for RHEL 5 Server - i386, x86_64

3. Description:

The Apache HTTP Server is a popular web server.

It was discovered that mod_proxy_ajp incorrectly returned an "Internal
Server Error" response when processing certain malformed requests, which
caused the back-end server to be marked as failed in configurations where
mod_proxy is used in load balancer mode. A remote attacker could cause
mod_proxy to not send requests to back-end AJP (Apache JServ Protocol)
servers for the retry timeout period (60 seconds by default) by sending
specially-crafted requests. (CVE-2010-0408)

A use-after-free flaw was discovered in the way the Apache HTTP Server
handled request headers in subrequests. In configurations where subrequests
are used, a multithreaded MPM (Multi-Processing Module) could possibly leak
information from other requests in request replies. (CVE-2010-0434)

This update also adds the following enhancement:

* with the updated openssl packages from RHSA-2010:0162 or RHSA-2010:0163
installed, mod_ssl will refuse to renegotiate a TLS/SSL connection with an
unpatched client that does not support RFC 5746. This update adds the
"SSLInsecureRenegotiation" configuration directive. If this directive is
enabled, mod_ssl will renegotiate insecurely with unpatched clients.

Refer to the following Red Hat Knowledgebase article for more details about
the changed mod_ssl behavior: http://kbase.redhat.com/faq/docs/DOC-20491

All users of JBoss Enterprise Web Server 1.0.1 should upgrade to these
updated packages, which contain backported patches to correct these issues
and add this enhancement. After installing the updated packages, Red Hat
Enterprise Linux 4 users must restart the httpd22 service, and Red Hat
Enterprise Linux 5 users must restart the httpd service, for the update to
take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

569905 - CVE-2010-0408 httpd: mod_proxy_ajp remote temporary DoS
570171 - CVE-2010-0434 httpd: request header information leak
