Applies to

Package: k_deflt
Product(s): SuSE Linux Enterprise Server 8 for IPF
Patch: patch-10216
Release: 20050531
Obsoletes: 8444ff7a9fd2f2d3d6cf52c0d64146d1


Everyone using the Linux Kernel on IPF architecture should update.



Problem description

This update fixes the following security problems:
  • when creating directories on ext2 filesystems the kernel did not zero initialize the memory allocated. Therefore potentially sensitive information could be exposed to users (CAN-2005-0400).
  • local users can crash the kernel via a crafted ELF library or executable, which causes a free of an invalid pointer (CAN-2005-0749).
  • local users could gain root access by causing a core dump of specially crafted ELF executables (CAN-2005-1263).
This update also addresses the following non-security problems:
  • fix files beeing truncated to four gigabytes on ext3
  • fix entries in /proc that caused 'top' to crash
  • fix kernel crash caused by busy inodes after umount
  • fix data corruption issue in MD multipath when retrying failed IO
  • enhanced locking in MD multipath and raid1
  • fix endless loop in IPsec
  • fix crash in XFS filesystem
i386 specific:
  • fix write performance problems on machines with more than 1GB memory

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 k_deflt-*.rpm for the default kernel image, or
  • rpm -Fvh k_itanium2-smp-*.rpm for the Itanium2 SMP kernel image, or
  • rpm -Fhv k_itanium2.rpm-*.rpm for the Itanium2 kernel image, or
  • rpm -Fhv k_smp-*.rpm for the SMP kernel 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.)
