RHEL 2.1 : apache (RHSA-2003:360)

High Nessus Plugin ID 12435


The remote Red Hat host is missing one or more security updates.


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.


Update the affected apache, apache-devel and / or apache-manual packages.
