Product(s): SUSE CORE 9 for AMD64 and Intel EM64T
- An NFS Direct I/O local denial of service could allow a local attacker to crash the machine.
- A previous smbfs security fix was faulty, writes did no longer work on smbfs shares.
- Unsigned vs signed problems in the generic scsi ioctl handler were reported by grsecurity. They have no impact due to the compiler using unsigned arithmetic, but are fixed nevertheless.
- ppos /proc file race conditions in the mapped_base and oom_adjust proc files were fixed.
- A bug in the pciconfig sysfs interface could cause incorrect values to be read from and written to PCI config space.
- A locking problem in CKRM could lead to a crash.
- In low memory situations, large writes would not be serviced in a timely fashion.
- The initialization of the bio->bi_bdev field was incorrect.
- VFS callouts for flock were added.
- MD on top of Device Mapper based devices was not working and lead to kernel crashes.
- Non-fatal errors encountered during readahead operations caused the device mapper multipath to fail the hardware path.
- A race condition in the kernel timer code could lead to kernel crashes under high load.
- An inetaddr notification problem with SCTP could lead to machine crashes.
- Lots of bugs and problems were fixed in the NSS Netware Storage System module.
- Several bugs in the DRBD device driver were fixed.
- CPU detection was moved to an earlier stage so that clustered APIC mode can be turned off reliably on AMD hardware.
- The 32bit vsyscall page was incorrectly marked GLOBAL which could lead to TLB corruptions.
- The number of MP busses was too low.
- A signedness issues in the signal register set lead to incorrect evaluation of systemcall results.
- A TLB context switch bug was partially fixed.
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 install it with either:
- rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
- rpm -Fvh kernel-syms*.rpm kernel-smp*.rpm for the SMP 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.)
