The security vulnerability that was reported to and verified by the Apache Software Foundation allows an attacker to potentially inflict serious damage on a server, and reveal sensitive information. Covalent strongly recommends that all affected customers apply the solution to their Covalent Apache servers as soon as possible. A simple one-line addition to the Apache configuration file, httpsd.conf, closes the vulnerability.
Prior to the first 'Alias' or 'Redirect' directive, add the following directive to the global server configuration:
RedirectMatch 400 "\\\.\."
Fixes for this vulnerability are also included in Apache HTTP server version 2.0.40. The 2.0.40 release also contains fixes for two minor path-revealing exposures. This release of Apache is available at http://www.apache.org/dist/httpd/
