- Due to insufficient checks of CPU register access from user-space while being in 32bit emulation of ptrace() a process can get kernel-level access to all system components.
- Paul Starzetz of iSEC reported a vulnerability in the mremap system call, which allows local attackers to crash the machine, and even to obtain super user privileges under some circumstances.
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 k_deflt.rpmfor the default kernel image, or
rpm -Fhv k_smp.rpmfor the SMP kernel image, or
rpm -Fhv k_numa.rpmfor the Numa kernel image
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.)
