Red Hat Security Advisory

Synopsis: Updated httpd packages fix mod_ssl security issue
Advisory ID: RHSA-2004:084-01
Issue date: 2004-03-23
Updated on: 2004-03-23
Product: Red Hat Enterprise Linux
Keywords: Apache httpd DoS SSL
Cross references:
Obsoletes:
CVE Names: CAN-2004-0113
----------------------------------------------------------------------

1. Topic:

Updated httpd packages are now available that fix a denial of service vulnerability in mod_ssl and include various other bug fixes.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, ppc64, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 3 - i386
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

A memory leak in mod_ssl in the Apache HTTP Server prior to version 2.0.49 allows a remote denial of service attack against an SSL-enabled server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0113 to this issue.

This update also includes various bug fixes, including:

- - improvements to the mod_expires, mod_dav, mod_ssl and mod_proxy modules

- - a fix for a bug causing core dumps during configuration parsing on the
IA64 platform

- - an updated version of mod_include fixing several edge cases in the SSI parser

Additionally, the mod_logio module is now included.

Users of the Apache HTTP server should upgrade to these updated packages, which contain backported patches that address these issues.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. 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/bugzilla for more info):

112771 - Invalid paths in config_vars.mk crash build of mod_jk
113934 - SRPMS: test for MMN version it too fragile
113929 - mod_expires headers not set when used in conjunction with mod_proxy
115328 - Satisfy keyword in httpd.conf causes apache to segfault on load
115379 - pcre conflict between httpd and php
