Thank you bliako, nice answer. I was thinking along the lines of using Perl to check the input length of the entry data, and reject it if it is longer than X many bytes.

    Then you may want to keep a database of buffer overflow sizes for each of these poisoned applications. Hehe! Be prepared for lots and lots of entries ... unfortunately. This latest sudo/linux vulnerability to go unnoticed for several years plus all the promotion of sudo (virtually every single howto page for OSX/Linux will mention sudo at least 10 times. Some will even say "sudo here is not necessary but it will do no harm".) makes me very sceptical, elevates my usually high scepticality factor by an order of magnitude. Or two.

    On the other hand I present ... PerlOS - and no that's not this.

    bw, bliako

      From what I can see now, the best way to make money programming is secretly put backdoors into software, and then secretly sell the exploit to the 3 letter agencies. Sudo makes it easy. :-)
