Problem description

This kernel update fixes the following security problems:

CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers. The default is that RH0 is disabled now. To adjust this, write to the file /proc/net/accept_source_route6.
CVE-2007-2453: The random number feature in the Linux kernel 2.6 (1) did not properly seed pools when there is no entropy, or (2) used an incorrect cast when extracting entropy, which might have caused the random number generator to provide the same values after reboots on systems without an entropy source.
CVE-2007-2876: A NULL pointer dereference in SCTP connection tracking could be caused by a remote attacker by sending specially crafted packets. Note that this requires SCTP set-up and active to be exploitable.
CVE-2007-3105: Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving "bound check ordering". Since this value can only be changed by a root user, exploitability is low.
CVE-2007-3107: The signal handling in the Linux kernel, when run on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency.
CVE-2007-2525: Memory leak in the PPP over Ethernet (PPPoE) socket implementation in the Linux kernel allowed local users to cause a denial of service (memory consumption) by creating a socket using connect, and releasing it before the PPPIOCGCHAN ioctl is initialized.
CVE-2007-3513: The lcd_write function in drivers/usb/misc/usblcd.c in the Linux kernel did not limit the amount of memory used by a caller, which allowed local users to cause a denial of service (memory consumption).
CVE-2007-3848: A local attacker could send a death signal to a setuid root program under certain conditions, potentially causing unwanted behaviour in this program.
CVE-2007-3851: On machines with a Intel i965 based graphics card local users with access to the direct rendering devicenode could overwrite memory on the machine and so gain root privileges.
Fixed a denial of service possibility where a local attacker with access to a pwc camera device could hang the USB subsystem. [#302194]

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:

rpm -Fvh kernel-*.rpm

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. 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.)
