SVN rev 193043 on 2009-05-29 16:24:23Z by stas
- 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]
