Apache Httpd < 2.2.15 : Subrequest handling of request headers (mod_headers)
A flaw in the core subrequest process code was fixed, to always provide a shallow copy of the headersin array to the subrequest, instead of a pointer to the parent request's array as it had for requests without request bodies. This meant all modules such as modheaders which may manipulate the inp...
