1. Topic:

Updated httpd packages that fix two minor security issues in the Apache Web
server are now available for Red Hat Enterprise Linux 3.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, 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.

An issue in the handling of regular expressions from configuration files
was discovered in releases of the Apache HTTP Server version 2.0 prior to
2.0.48. To exploit this issue an attacker would need to have the ability
to write to Apache configuration files such as .htaccess or httpd.conf. A
carefully-crafted configuration file can cause an exploitable buffer
overflow and would allow the attacker to execute arbitrary code in the
context of the server (in default configurations as the 'apache' user).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-0542 to this issue.

Users of the Apache HTTP Server should upgrade to these erratum packages,
which contain backported patches correcting these issues, and are applied
to Apache version 2.0.46.  This update also includes fixes for a number of
minor bugs found in this version of the Apache HTTP Server.

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.

If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate.  The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:

https://rhn.redhat.com/help/latest-up2date.pxt

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

110434 - CAN-2003-0542 local buffer overflow in config file parsing
105725 - long httpd graceful reload times
