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:
  • Limit the maximum number of LUNs to 16384 [#185164]
  • LSI 1030/MPT Fusion driver hang during error recovery -- Optionally disable QAS [#180100]
  • advance buffer pointers in h_copy_rdma() to avoid data corruption [#186444]

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
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. If you are using GRUB you don't need to do anything.
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.)
