This update should be installed on all systems for security reasons.
This article applies to systems with the k_i386 kernel package installed, please use the appropriate kernel package if you are using a different kernel:
You can find out which kernel package you are using with
rpm -qf /boot/vmlinuz




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 user "root":
echo /no/such/file >/proc/sys/kernel/modprobe


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 this command:
rpm -Uvh k_i386.rpm
Please make sure that you execute the commands
mk_initrd lilo
as user "root" after installing this update for the system to be bootable.
Furthermore, if you are upgrading from kernel 2.4.7 please make sure to install the updated kernel utils as described in the maintenance web articles
as well.
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.)
