Problem description

This kernel update fixes several security problems:

CVE-2006-1524: shmat: stop mprotect from giving write permission to a readonly shared memory attachment.
CVE-2006-1864: Due to incorrect argument checking it was possible to break out of chroots on smbfs filesystems.
CVE-2006-1342: A minor information leak in SO_ORIGINAL_DST was fixed.
CVE-2005-4798: Creation of long symlinks on the NFS server could crash the client machine.
CVE-2006-1056: i386/x86-64: Fix AMD x87 information leak between processes.
CVE-2006-0741: x86_64 only: Always check that RIPs are canonical during signal handling, otherwise local attackers could crash the machine.
CVE-2006-0742: IA64 only: Don't declare die_if_kernel as noreturn, otherwise local attackers can crash the machine.

Additional following bugs were fixed:

reiserfs: don't BUG() in panic
nfs client: handle long symlinks properly
SCSI-Tape: zero-initialize scatter-gather list
PowerPC64: sys_rt_sigreturn should return a long instead of int.
SCSI-Tape driver: Zero-initialize scatter-gather list to avoid BUGs.
IA64: don't declare die_if_kernel as noreturn

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 install by using the following command:

rpm -qf /boot/vmlinuz

Download the kernel image fitting your setup and install it with either:

rpm -Fvh k_deflt-*.rpm for the default kernel image, or
rpm -Fvh k_itanium2-smp-*.rpm for the Itanium2 SMP kernel image, or
rpm -Fhv k_itanium2.rpm-*.rpm for the Itanium2 kernel image, or
rpm -Fhv k_smp-*.rpm for the SMP 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.)
