phonet: some signedness bugs
Dan Rosenberg pointed out that there were some signed comparison bugs
in the phonet protocol.
http://marc.info/?l=full-disclosure&m=129424528425330&w=2
The problem is that we check for array overflows but "protocol" is
signed and we don't check for array underflows. If you have already
have CAP_SYS_ADMIN then you could use the bugs to get root, or someone
could cause an oops by mistake.
