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 oops on io scheduler unload on a process without ioc (backport)
  • OCFS2 updated to to version 1.2.3.
  • update patches.arch/ppc-update_gtod-race.patch: restrict to 64bit only because it leads to deadlocks on ppc32 [#202146]
  • Fix MCA recovery in context switch path [#199472]
  • fix gettimeofday vs. update_gtod race [#197699]
  • LKCD: dump all slab pages. [#196330]
  • Make idle io be lowest priority best-effort [#195387]
  • Fix dropping of wrong cic. [#195387]
  • Fix stale file handle problem with subtree_checking. [#195040]
  • Remove Altix PROM bit that can race on MCAs. [#193296]
  • Prevent silent data corruption caused by XPC. [#193132]
  • Fix race condition during COW [#192259]
  • sched: fix group power for allnodes_domains [#191929]
  • Allow dma_alloc_coherent() to work for regions up to 2MB. [#191615]
  • 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]
  • MPT driver: Fix oops on module loading [#189534]
  • SUNRPC: Ensure that rpc_mkpipe returns a refcounted dentry [#183013]
  • 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]
  • KPROBES: Fix system panic if user doing copy_from_user in the probe handlers [#171483]
  • Avoid possible soft-lockup, particularly related to md [#152099]
  • reiserfs: fix transaction overflowing [#145070]

Solution

Please install the updates provided at the location noted below.

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 use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with:
rpm -Fvh kernel-*.rpm
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:
mk_initrd lilo
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.)
