This patch updates your kernel-source package and is only necessary if you compile your own kernel.




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


The kernel-source RPM package only contains the source code for the SuSE version of the kernel. As such, it does not actively fix any of the mentioned problems directly. Moreover, it provides the administrator with a new source code tree if the administrator should chose to build a kernel with an own configuration. If you are running a self-compiled kernel, you should recompile your kernel and install the results. If you are running pre-built kernels, you should refer to the updates of the packages k_deflt, k_smp, k_psmp or k_i386 depending on what package is installed on your system.

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 kernel-source.rpm
