lighttpd -- Remote DOS in CRLF parsing

Lighttpd SA:

If the connection aborts during parsing “\r\n\r\n” the server
might get into a infinite loop and use 100% of the CPU time.
lighttpd still responses to other requests. This can be repeated
until either the server limit for concurrent connections or file
descriptors is reached.
The bug was reported and fixed by Robert Jakabosky.
