solutions Security update for Linux kernel SuSE Linux Maintenance Web (b0f1248576f4ba7a88b35a839945b272)

Applies to

Product(s): SuSE Linux Enterprise Server 8 for IPF

Release: 20040210
Obsoletes: none


Everyone using the Linux kernel on IPF architecture should update.



Problem description

This kernel update addresses several security problem that can lead
from local denial-of-service to local root access:
  • Vicam USB driver: CAN-2004-0075
    • denial-of-service due to problem while copying data from user to kernel space
  • Direct Render Infrastructure: CAN-2004-0003
    • denial-of-service due to integer overflow
    • needs r128 card and console to be exploited
  • ncpfs/ncp_lookup: CAN-2004-0010
    • buffer overflow with the possibility to gain root
  • execve():
    • malformed elf binaries can lead to a local denial-of-service attack
  • mremap(): CAN-2004-0077
    • a new bug found by Paul Starzetz that can lead to local root access
Additionally, a few bugfixes are included, fixing problems with
SCSI starvation, ACPI, lvm-mp, LAuS, aacraid and NFS. The qla2x00_conf
modules were enabled.
The kernel's memory management was not well tuned for handling
machines with >= 8GB of memory and with applications using large
amounts of non-locked shared memory, such as SAP. For these situations,
setting the new /proc/sys/vm/vm_shmem_swap sysctl to 1 helps.

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 either:
  • rpm -Fvh k_deflt.rpm for the default kernel image, or
  • rpm -Fvh k_smp.rpm for the SMP kernel image, or
  • rpm -Fhv k_itanium2.rpm for the Itanium 2 kernel image, or
  • rpm -Fhv k_itanium2-smp.rpm for the Itanium 2 SMP kernel image
(Note: only install one of these kernels, not all of them.)
If you need the kernel sources you can install them by using the command:
rpm -Uvh kernel-source.rpm
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.)
