Product(s): SUSE CORE 9 for IBM POWER
- when creating directories on ext2 filesystems the kernel did not zero initialize the memory allocated. Therefore potentially sensitive information could be exposed to users (CAN-2005-0400).
- local users can crash the kernel via a crafted ELF library or executable, which causes a free of an invalid pointer (CAN-2005-0749).
- local users could gain root access by causing a core dump of specially crafted ELF executables (CAN-2005-1263). The problem is believed to be not exploitable on kernel 2.6, we included the patch nevertheless.
- fix NFS corrupting renamed files
- fix Oops in acl code
- fix building the kernel package with the 'build' program
- fix performance problems due to inode cache size
- fix potential deadlock when renaming files
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-syms*.rpm kernel-default*.rpmfor the default kernel image, or
rpm -Fvh kernel-syms*.rpm kernel-iseries64*.rpmfor the 64 bit iSeries kernel image, or
rpm -Fvh kernel-syms*.rpm kernel-pseries64*.rpmfor the 64 bit pSeries kernel image, or
rpm -Fvh kernel-syms*.rpm kernel-smp*.rpmfor the SMP kernel image, or
rpm -Fvh kernel-syms*.rpm kernel-pmac64*.rpmfor the 64 bit PPC kernel image
After performing the RPM package update of your kernel package, you must execute the following commands as root to make sure that your system will start up again:
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.)
