The thing about noexec is that you can almost always circumvent it. If you have a shell script in /tmp that you want to execute, you can use "sh /tmp/r00tk1t". If you have a binary, "/lib/ld-linux.so.2 /tmp/r00tk1t". It's a bit like non-executable stacks; right now it will probably break a lot of existing exploits, but for the most part only fairly trivial modifications are needed to make them work again. So it doesn't really buy you any extra security. p. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
