A flaw was found in the apr_fnmatch() function of the bundled APR library. Where mod_autoindex is enabled, and a directory indexed by mod_autoindex contained files with sufficiently long names, a remote attacker could send a carefully crafted request which would cause excessive CPU usage. This could be used in a denial of service attack.
Workaround: Setting the ‘IgnoreClient’ option to the ‘IndexOptions’ directive disables processing of the client-supplied request query arguments, preventing this attack.
Resolution: Update APR to release 1.4.5 (bundled with httpd 2.2.19) or release 0.9.20 (bundled with httpd 2.0.65)
