Product(s): SUSE CORE 9 for Itanium Processor Family
- 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. This bug was already fixed in openSUSE 10.2 and SLES10.
- The handling of the usage counter for bond devices was fixed.
- 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 wake-up 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. This was already fixed for SLES10.
- CVE-2007-2525: A memory leak in the PPPoE driver can be abused by local users to cause a denial-of-service condition. This bug was already fixed for SLES10.
- CVE-2007-3848: Local users are allowed to send arbitrary signals to child processes running with different UID. This bug was already fixed for SLES10
- CVE-2007-4573: It was possible for local user to become root by exploiting a bug in the IA32 system call emulation. This affects x86_64 platforms with kernel 2.4.x and 2.6.x before 188.8.131.52 only.
- CVE-2007-4571: An information disclosure vulnerability in the ALSA driver can be exploited by local users to read sensitive data from the kernel memory.

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 either:
- rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
- rpm -Fhv kernel-syms*.rpm kernel-smp*.rpm for the SMP kernel image with support for up to 64 GB, or
- rpm -Fhv kernel-syms*.rpm kernel-bigsmp*.rpm for the SMP kernel image with support for up to 64 GB
In case you are using LILO as bootmanager, please make sure that you also execute the command
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.)
