Problem description

This kernel update fixes the following security problems:

CVE-2006-4145: The Universal Disk Format (UDF) filesystem driver allowed local users to cause a denial-of-service.
CVE-2006-6106: Multiple buffer overflows in the cmtp_recv_interopmsg function in the Bluetooth driver allowed remote attackers to cause a denial-of-service and possibly execute arbitrary code via CAPI messages.
CVE-2007-0773: Local users can exploit a bug in the kernel to cause a denial-of-service (kernel OOPS) via fput in a 32-bit ioctl on a 64-bit x86 system.
CVE-2007-4573: It was possible for local user to become root by exploitable a bug in the IA32 system call emulation. This affects x86_64 platforms with kernel 2.4.x and 2.6.x before 2.6.22.7 only.

and the following non security bugs:

patches.common/reiserfs-bkl-inversion: fix reiserfs lock inversion of bkl vs inode semaphore [#116531]
patches.common/reiserfs-generic-open.diff: reiserfs: use generic_file_open for open() checks [#182097]

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 either:

rpm -Fvh k_deflt-2.4.*.rpm for the default kernel image, or
rpm -Fhv k_smp-2.4.*.rpm for the SMP kernel image, or
rpm -Fhv k_numa-2.4.*.rpm for the NUMA kernel image

Please do only install one of these kernels, not all of them.
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.)
