Summary
Apache HTTP Server is prone to a denial of service (DoS) vulnerability.
Insight
Insight
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.
