Problem description

This kernel update fixes the following security problems:
  • CVE-2006-3626: A race condition allows local users to gain root privileges by changing the file mode of /proc/self/ files in a way that causes those files (for instance /proc/self/environ) to become setuid root. [#192688]
  • CVE-2006-2935: A stackbased buffer overflow in CDROM / DVD handling was fixed which could be used by a physical local attacker to crash the kernel or execute code within kernel context, depending on presence of automatic DVD handling in the system. [#190396]
  • CVE-2006-2451: Due to an argument validation error in prctl(PR_SET_DUMPABLE) a local attacker can easily gain administrator (root) privileges. [#186980]
and the following non security bugs:
  • XEN patches/fixes:
    • kunmap_atomic() must zap the PTE to avoid dangling references.
    • patches.xen/xen-balloon-max-target: Expose limit domain can be ballooned up to [#152667]

  • Fix race condition during COW [#192259]
  • sched: fix group power for allnodes_domains [#191929]

  • fix ABBA deadlock between cpuset callback_sem and hotplug cpucontrol mutex [#191582]
  • Check for existing sysfs directory prior to creating one [#191360]
  • Fix possible NFS panic in readdir. [#189951]

  • Pass file mode on DMAPI remove events [#182691]
  • MPT driver: Fix oops during error recovery [#177919]
  • flush icache on POWER4 cpus to fix itrace crash [#171699]

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system.
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:
rpm -Fvh kernel-*.rpm
Please do only install one of these kernels, not all of them.
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.)
