I'm wonder if anyone happens to have a simplier (slower) version of bsd-snprintf.c. It seems NeXT 3.3 (unsure about 4.2) is missing mprotect(). If I could get something to replace that for a while and fix some of theses utmp in login.c issues I may have a rough port NeXT to black hardware.=) Thanks

I'm reading this fine article on O'Reilly: http://linux.oreillynet.com/lpt/a//linux/2001/11/08/ssh_keystroke.html <quote> The paper concludes that the keystroke timing data observable from today's SSH implementations reveals a dangerously significant amount of information about user terminal sessions--enough to locate typed passwords in the session data stream and reduce the

...certain values of extra_pad, block_size and len. Firstly, the computation roundup(state->extra_pad, block_size) can return 0 for certain values of extra_pad and block_size. This causes state->extra_pad = 0 but this variable is used subsequently in a modular operation. Secondly, the assignment padlen += pad might overflow for certain values of extra_pad, padlen and block_size. This can cause the length of the padding appended to the outgoing packet to be strictly less than 4; because no sanity check on the padding length follows the adding of extra padding. The computation roundup(state->e...
