solutions Security update for Linux kernel SuSE Linux Maintenance Web (91e977c7e67c3b27c1652d59fa4ff24e)

Applies to

Package: k_deflt
k_numa
k_smp
kernel-source
Product(s): SuSE Linux Enterprise Server 8 for AMD64
Patch: patch-10863
Release: 20060214
Obsoletes: 77fd150f1962b32355a96affeee048ed

Indications

Everyone using the Linux Kernel on x86_64 architecture should update.

Contraindications

None.

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 use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
  • rpm -Fvh k_deflt-2.4.*.rpm for the default kernel image, or
  • rpm -Fhv k_smp-2.4.*.rpm for the SMP kernel image, or
  • rpm -Fhv k_numa-2.4.*.rpm for the NUMA 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.)
