Problem description

This update fixes the following security problems:
  • CVE-2005-3623: Remote users could set ACLs even on read-only exported NFS filesystems and so circumvent access control.
  • CVE-2004-1058: A race condition was fixed which could allow local users to read environment variables of another process. This is a reissue of an earlier fix in the 2.6 kernel also present in the 2.4 kernel.
  • CVE-2005-2553: Fixed an oops when a 64bit binary was traced with a 32bit ltrace. This problem only affects the x86-64 platform.
Also the following bugs were fixed:
  • Allow building the kernel with newer binutils.
  • Validate NFS inodes returned by cached lookups to avoid spurious stale NFS file handles.
  • Retry failing allocations on ext3 filesystems multiple times, in case space is freed on pending ext3 journal releases.

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 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.)
