Updated Apache httpd packages to correct two security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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

Watchfire reported a flaw that occured when using the Apache server as an HTTP proxy. A remote attacker could send an HTTP request with both a ‘Transfer-Encoding: chunked’ header and a ‘Content-Length’ header.
This caused Apache to incorrectly handle and forward the body of the request in a way that the receiving server processes it as a separate HTTP request. This could allow the bypass of Web application firewall protection or lead to cross-site scripting (XSS) attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-2088 to this issue.

Marc Stern reported an off-by-one overflow in the mod_ssl CRL verification callback. In order to exploit this issue the Apache server would need to be configured to use a malicious certificate revocation list (CRL). The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-1268 to this issue.

Users of Apache httpd should update to these errata packages that contain backported patches to correct these issues.
