solutions Security update for kernel SuSE Linux Maintenance Web (d616efaaa3764b063cc5bd3d6d09c89e)

Novell Linux Desktop 9 for x86
- 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 download and use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and the kernel symbols (kernel-syms*.rpm) and install it with either:
- rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
- rpm -Fhv kernel-syms*.rpm kernel-smp*.rpm for the SMP kernel image with support for up to 64 GB, or
- rpm -Fhv kernel-syms*.rpm kernel-bigsmp*.rpm for the SMP kernel image with support for up to 64 GB
In case you are using LILO as bootmanager, please make sure that you also execute the command
after installing the update for the system to remain bootable.
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.)
