- Prevent buffer overflow in IPFilter's load_http function used to load   ipfilter tables via http by the user-level ippool utility. Previously   the 1024-byte buffer used to store a http request coudld easily overflow   if the length of the hostname part of the url passes exceeded 496 bytes. [1] - Use snprintf to prevent possieble buffer overflows in future. [2] - Do not try to close the descriptor twice on failure. [2]
