When a Content-Length parameter is received from the client, SurgeFTP
tries to allocate the amount of memory (max 2147483647 bytes) specified
in this field and then copies the data in the resulted new buffer.
The problem is in the lack of checks on the result of the allocation
which leads to the crash of the entire server during the copying of the
data to a NULL pointer if that amount of memory cannot be allocated.
