Problem description

This update addresses various security related bugs within the Linux kernel which could allow local attackers to either elevate their priveleges or to cause a DoS (Denial of Service) attack. The fixes consist of:
  • fix for the memleak in do_fork()
  • fix for the MCAST/setsockopt() buffer overflow (CAN-2004-0424)
  • fix for a permission problem on /proc/scsi/qla2300/HbaApiNode
  • fix for the buffer overflow in panic() (CAN-2004-0394)

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 -Fvh kernel-iseries64-2.4.*.rpm for the iSeries kernel image, or
  • rpm -Fhv kernel-ppc64-2.4.*.rpm for the pSeries kernel image
(N.B.: only install one of these kernels, not all of them.)
Please make sure that you also execute the commands
mk_initrd lilo
after installing the update for the system to remain bootable.
Finally, reboot the system with
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.)
