connection: Prevent pointer overflow from large lengths.
If the remote side sends sufficiently large `length` field, it will overflow the `p` pointer. Technically it is undefined behavior, in practice it makes `p < end`, so the length check passes. Attempts to access the data later causes crashes. This issue manifests only on 32bit systems, but the behavior is undefined everywhere.
