Re: HTTP REQUEST_METHOD flaw

The other obvious implication is the REQUEST_METHOD environment variable.

Just the possibility of an overflow or someone's ill kept script only recognizing
2 different possible request methods, and causing it to act oddly.

The problem relates to "allowable" REQUEST_METHODs when a dynamic resource,
such  as a CGI script is requested. Essentially _any_ (except for HEAD,
TRACE and OPTIONS) REQUEST_METHOD can be used - even methods not defined in
the HTTP protocol. Consider the following requests which all return the
requested resource.
