been upgraded to Linux kernel version 2.4.23, which fixes a bug in the
kernel's do_brk() function that could be exploited to gain root
privileges. These updated kernels and modules should be installed by
any sites running a 2.4 kernel earlier than 2.4.23. Linux 2.0 and 2.2
kernels are not vulnerable."
