(Last modified: 15OCT2004)

solutions Security update for Linux kernel SuSE Linux Maintenance Web (b82467862cb95a39a359829959673c39)

Applies to

Package: kernel-64k-pagesize
Product(s): SUSE CORE 9 for Itanium Processor Family
Patch: patch-9415
Release: 20041015
Obsoletes: a0319e88221f6537054ec2693485b82d


Everyone using the Linux Kernel on IPF architecture should update.



Problem description

Security Fixes:
  • With the iptables firewall enabled in a certain configuration (as done by SuSEFirewall2) a handcrafted IP packet from a remote attacker could crash the machine.
  • s390: The privileged "sacf" instruction was not correctly protected, so local users could gain root access.
  • Some minor addition proc information leaks were fixed.
Bug fixes:
  • 2 CD writing problems were fixed, one in BIO handling and one in highmem bounce buffer handling (machines with more than 1GB RAM).
  • A problem with write barriers not being issued on IDE drives that default to write cache off was fixed.
  • Make sure O_SYNC writes return -EIO for write errors.
  • Some bio related fixes for the ASMlib kernel driver.
  • Support for O_NOATIME in open(2) system call, fixing an LVM related problem.
  • Do not clear/remove referenced pages in BLKFLSBUF ioctl.
  • Fixed an iptables logging Oops caused by ifdown/ifup sequences.
  • Do not propagate TCP errors to nfsd to avoid having nfsd dieing.
  • Fixed some RAID 1 problems for read retry problems and device removal.
  • Do not dirty inherited ACLs.
  • Don't attach upper level SCSI drivers to raid control ports, such as the LSI/Engenio.
  • Fixed a USB 2.0 EHCI problem with list scanning on SMP systems.
  • Fixed a memory corruption in libata.
Architecture specific bug fixes:
  • ia64: Fixed a race in fsys_gettimeofday on IPF.
  • ia64: Fixed crash in perfmonctl syscall.

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 install by using the following command:
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
  • rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
  • rpm -Fvh kernel-syms*.rpm kernel-64k-pagesize*.rpm for the 64k page size kernel image, or
  • rpm -Fhv kernel-syms*.rpm kernel-sn*.rpm for the SGI SN2 (Altix) image
Please do only install one of these kernels, not all of them.
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.)
