[Devil-linux-develop] Buffer flow compiler mods from Immunix.org

[John v. V. <joh...@ya...>]

While looking thru the LinuxISO site I clicked on Immunix.

They have two features for their distro which prevent attacks.  The one that
got my attention deals w/ buffer overflows by using canaries, yeah the birds
;), in GCC.

Well, they are about to stop giving linux away, selling it only, but their mods
to the compiler are GPL.

There is a really mild perfomance hit, nothing to speak of.

The other thing is format guarding, something to do w/ printf and sprintf, I
never heard of it, but i would hate to hear about it by being cracked into !!
