Hi,

Maybe this has been discussed earlier today on this list, but I've just joined it.

I was told that doing a 'limit -v 2097151' would work around the do_brk() bug. Unfortunately it does not :-(

The sample exploit posted on bugtraq manages to reboot my SuSE 8.2 machine (standard kernel) despite the ulimit.

Hi Erik, Roman in hiw original post suggested two other things needed to be done to install this work around: Add the line ulimit -v 2097151 as the second lines of /etc/init.d/rc and /etc/profile, and then execute the command itself in your shell and then restart all daemons that allow logins (xdm, sshd, inetd/xinetd, ...). Alternatively, simply reboot after adding the lines to above files: Roman said this workaround is Courtesy of Solar Designer. (Note: The reboot is in lieu of restarting all daemons and not the editing of /etc/init.d/rc and /etc/profile.) Further Note: the above limit -v # was changed to reflect Roaman's second post.) It would be best to Read, the entire thread "RE: [suse-security] Bugs on Kernel 2.4" at: http://lists.suse.com/archive/suse-security/2003-Dec/ Redhat has already put up their patch rpm, I suspect SuSe's will be up soon, making this work around moot.
