Problem description

Various security related bugs have been fixed inside the Linux kernel which could allow local attackers to either elevate their privileges or to cause a DoS attack. The fixes consist of
  • a fix for the memleak in do_fork()
  • a fix for the buffer overflow in panic() (CAN-2004-0394)


Please install the updates provided at the location noted below.

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system.
First, find out which kernel package to use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
  • rpm -Fhv k_deflt.rpm for the default kernel, or
  • rpm -Fhv k_psmp.rpm for the PSMP kernel image, or
  • rpm -Fhv k_smp.rpm for the SMP kernel image, or
  • rpm -Fhv k_i386.rpm for the i386 kernel image
(Note: only install one of these kernels, not all of them).
The kernel sources can be installed using the following command:
rpm -Uvh kernel-source.rpm
After performing the RPM package update of your kernel package, you must execute the following commands as root to make sure that your system will start up again:
mk_initrd lilo
Note: If you do not execute the commands above, your system might be in an unbootable state. To ensure that the fixes become active, you should reboot your system usingthe command
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
