Posted on: 07/25/2005 07:38 AM

A httpd security update has been released for Red Hat Enterprise Linux 3 and 4

----------------------------------------------------------------------
Red Hat Security Advisory

Synopsis: Moderate: httpd security update
Advisory ID: RHSA-2005:582-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-582.html
Issue date: 2005-07-25
Updated on: 2005-07-25
Product: Red Hat Enterprise Linux
CVE Names: CAN-2005-1268 CAN-2005-2088
----------------------------------------------------------------------

1. Summary:

Updated Apache httpd packages to correct two security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

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
