Summary
Red Hat Security Advisory: : Updated httpd packages fix Apache security vulnerabilities
Notes
Topic
Updated httpd packages that fix two minor security issues in the Apache Web
server are now available for Red Hat Linux 8.0 and 9.
Details
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.
A bug in the CGI daemon-based "mod_cgid" module was discovered that can
result in CGI script output being sent to the wrong client. This issue only
affects Red Hat Linux 9, and only when the server is configured to use the
"worker" MPM. The default configuration uses the "mod_cgi" module for CGI
and is not affected by this issue. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2003-0789 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 2.0.40.
