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.

Installation notes

This update is provided as a RPM packages that can easily be installed onto a running system by the following command:
rpm -Fvh kernel-syms*.rpm kernel-default*.rpm
Afterwards, reboot the system with
shutdown -r now
