Problem description

This kernel update fixes the following security problems:

CVE-2006-2936: The ftdi_sio driver allowed local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued. This requires this driver to be loaded, which only happens if such a device is plugged in.
CVE-2006-4814: A deadlock in mincore that could be caused by local attackers was fixed.
CVE-2006-6106: Multiple buffer overflows in the cmtp_recv_interopmsg function in the Bluetooth driver net/bluetooth/cmtp/capi.c) in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via CAPI messages with a large value for the length of the (1) manu (manufacturer) or (2) serial (serial number) field.
CVE-2006-5749: The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux kernel does not call the init_timer function for the ISDN PPP CCP reset state timer, which has unknown attack vectors and results in a system crash.
CVE-2006-5753: Unspecified vulnerability in the listxattr system call in Linux kernel, when a "bad inode" is present, allows local users to cause a denial of service (data corruption) and possibly gain privileges.
A remote denial of service problem on NFSv2 mounts with ACL enabled was fixed.

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 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

lilo

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.)
