Make sure to allocate enough memory in buffers for the operations they are used for, and to check/enforce buffer sizes when performing those memory operations. Properly allocate and free memory. Make a best effort at allocating memory for the network hardware address (remove code for Apple platforms). Try to consume all of the remaining content if a valid Content-Length header was provided. Check for success when attempting to acquire mutexes.
