Description

This update fixes a security vulnerability in the Linux kernel
(CAN-2003-0127). The vulnerability allows a local unprivileged attacker to
gain root privileges by using ptrace/strace in
combination with automatic kernel module loading on request, also known
as "kmod".
As a temporary workaround, it is possible to disable the automatic loading of kernel modules by running the following command as root:
echo /no/such/file >/proc/sys/kernel/modprobe
If you do not use the grub bootloader, you should make sure that the boot blocks are initialized after you have successfully performed this kernel update to ensure that your system will start after a reboot.

Solution

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 by using these commands:
rpm -Uvh k_itanium2-smp.rpm
After installation of the kernel RPM 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.)
