"Updated Apache packages that fix a minor security issue are now
available for Red Hat Enterprise Linux.

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 1.3
prior to 1.3.29. 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 CVE-2003-0542 to this
issue.

This update also includes an alternative version of the httpd binary
which supports setting the MaxClients configuration directive to
values above 256.

All users of the Apache HTTP Web Server are advised to upgrade to the
applicable errata packages, which contain back-ported fixes correcting
the above security issue.

Note that the instructions in the 'Solution' section of this errata
contain additional steps required to complete the upgrade process."
