______________________________________________________________________________
1) problem description, brief discussion
The Linux kernel is the core component of the Linux system.
Several vulnerabilities were reported in the last few weeks which
are fixed by this update.
Not all kernels are affected by all the problems, each of the problems
has an affected note attached to it.
The CAN-XXXX-XXX IDs are Mitre CVE Candidate IDs, please see
http://www.mitre.org for more information.
Following security vulnerabilities are fixed:
- CAN-2005-0449: The netfilter/iptables module in Linux before 2.6.8.1
allows remote attackers to cause a denial of service (kernel crash)
or bypass firewall rules via crafted packets, which are not properly
handled by the skb_checksum_help function.
A remote attacker could crash a SUSE Linux system when this system
is used as a router/firewall.
Only SUSE Linux versions using the 2.6 kernels are affected.
- CAN-2005-0209: When forwarding fragmented packets, we can only
use hardware assisted checksum once.
This could lead to a denial of service attack / crash potentially
trigger able by remote users.
Only SUSE Linux versions using the 2.6 kernels are affected.
- CAN-2005-0529: Linux kernels before 2.6.11 use different size types
for offset arguments to the proc_file_read and locks_read_proc
functions, which leads to a heap-based buffer overflow when a signed
comparison causes negative integers to be used in a positive context.
Only SUSE Linux versions using the 2.6 kernels are affected.
- CAN-2005-0530: Signedness error in the copy_from_read_buf function in
n_tty.c before Linux kernel 2.6.11 allows local users to read
kernel memory via a negative argument.
Only SUSE Linux versions using the 2.6 kernels are affected.
- Missing checking in the epoll system calls allowed overwriting of
a small range of kernel memory. This allows a local attacker
to gain root privileges.
All SUSE Linux versions except SUSE Linux 8.2 are affected.
- A integer overflow was possible when writing to a sysfs file, allowing
an attacker to overwrite kernel memory.
Only SUSE Linux versions using the 2.6 kernels are affected.
- CAN-2005-0532: The reiserfs_copy_from_user_to_file_region function in
reiserfs/file.c before Linux kernel 2.6.11, when running on 64-bit
architectures, may allow local users to trigger a buffer overflow as
a result of casting discrepancies between size_t and int data types.
This allows a remote attacker to overwrite kernel memory, crash
the machine or potential get root access.
Only SUSE Linux versions using the 2.6 kernels running on 64 bit
machines are affected.
- CAN-2005-0384: Fixed a local denial of service attack in the kernel
PPP code. This allows a local attacker to hang the system.
All SUSE Linux versions are affected.
- CAN-2005-0210: A dst leak problem in the ip_conntrack module of the
iptables firewall was fixed.
Only SUSE Linux versions using the 2.6 kernels are affected.
- CAN-2005-0504: Buffer overflow in the MoxaDriverIoctl function for
the moxa serial driver (moxa.c) in Linux 2.2.x, 2.4.x, and 2.6.x allows
local users to execute arbitrary code via a certain modified length value.
Only SUSE Linux versions using the 2.6 kernels are fixed, this
was considered too minor for our 2.4 line.
- Only root should be able to set the N_MOUSE line discipline, this
is a partial fix for CAN-2004-0814.
- Due to an xattr sharing bug in the ext2 and ext3 file systems, default
ACLs could disappear.
Only SUSE Linux versions using the 2.6 kernels are affected.
- CAN-2005-0003: Fixed a potential problem with overlapping VMAs also
on 2.4 kernels.
Only SUSE Linux versions using the 2.4 kernels are affected.
- CAN-2004-1333: Fixed a local denial of service problem with the
VC_RESIZE ioctl. A local user logged in to a text console can crash
the machine.
Only SUSE Linux versions using the 2.4 kernels are affected.
Additional kernel module had bugs fixed:
- antivir / dazuko.ko: The capability handling of this module was broken
and was fixed by a version upgrade.
- drbd: A slow memory leak in drbd was fixed.
- Bugs fixed after the SUSE Linux Enterprise Server 8 SP4 release
(for the SLES 8 and United Linux 1 updates).
- Bugs fixed after the SUSE Linux Enterprise Server 9 SP1 release
(for the SLES 9 and NLD 9 updates).
2) solution/workaround
None. Please install the updated packages.
3) special instructions and notes
SPECIAL INSTALL INSTRUCTIONS:
==============================
The following paragraphs will guide you through the installation
process in a step-by-step fashion. The character sequence "****"
marks the beginning of a new paragraph. In some cases, the steps
outlined in a particular paragraph may or may not be applicable
to your situation.
Therefore, please make sure to read through all of the steps below
before attempting any of these procedures.
All of the commands that need to be executed are required to be
run as the superuser (root). Each step relies on the steps before
it to complete successfully.
**** Step 1: Determine the needed kernel type
Please use the following command to find the kernel type that is
installed on your system:
rpm -qf /boot/vmlinuz
Following are the possible kernel types (disregard the version and
build number following the name separated by the "-" character)
k_deflt # default kernel, good for most systems.
k_i386 # kernel for older processors and chip sets
k_athlon # kernel made specifically for AMD Athlon(tm) family processors
k_psmp # kernel for Pentium-I dual processor systems
k_smp # kernel for SMP systems (Pentium-II and above)
k_smp4G # kernel for SMP systems which supports a maximum of 4G of RAM
kernel-64k-pagesize
kernel-bigsmp
kernel-default
kernel-smp
**** Step 2: Download the package for your system
Please download the kernel RPM package for your distribution with the
name as indicated by Step 1. The list of all kernel rpm packages is
appended below. Note: The kernel-source package does not
contain a binary kernel in bootable form. Instead, it contains the
sources that the binary kernel rpm packages are created from. It can be
used by administrators who have decided to build their own kernel.
Since the kernel-source.rpm is an installable (compiled) package that
contains sources for the linux kernel, it is not the source RPM for
the kernel RPM binary packages.
The kernel RPM binary packages for the distributions can be found at the
locations below ftp://ftp.suse.com/pub/suse/i386/update/.
8.2/rpm/i586
9.0/rpm/i586
9.1/rpm/i586
9.2/rpm/i586
After downloading the kernel RPM package for your system, you should
verify the authenticity of the kernel rpm package using the methods as
listed in section 3) of each SUSE Security Announcement.
**** Step 3: Installing your kernel rpm package
Install the rpm package that you have downloaded in Steps 3 or 4 with
the command
rpm -Uhv --nodeps --force
where is the name of the rpm package that you downloaded.
Warning: After performing this step, your system will likely not be
able to boot if the following steps have not been fully
followed.
**** Step 4: configuring and creating the initrd
The initrd is a ramdisk that is loaded into the memory of your
system together with the kernel boot image by the bootloader. The
kernel uses the content of this ramdisk to execute commands that must
be run before the kernel can mount its actual root filesystem. It is
usually used to initialize SCSI drivers or NIC drivers for diskless
operation.
The variable INITRD_MODULES in /etc/sysconfig/kernel determines
which kernel modules will be loaded in the initrd before the kernel
has mounted its actual root filesystem. The variable should contain
your SCSI adapter (if any) or filesystem driver modules.
With the installation of the new kernel, the initrd has to be
re-packed with the update kernel modules. Please run the command
mk_initrd
as root to create a new init ramdisk (initrd) for your system.
On SuSE Linux 8.1 and later, this is done automatically when the
RPM is installed.
**** Step 5: bootloader
If you run a SUSE LINUX 8.x, SLES8, or SUSE LINUX 9.x system, there
are two options:
Depending on your software configuration, you have either the lilo
bootloader or the grub bootloader installed and initialized on your
system.
The grub bootloader does not require any further actions to be
performed after the new kernel images have been moved in place by the
rpm Update command.
If you have a lilo bootloader installed and initialized, then the lilo
program must be run as root. Use the command
grep LOADER_TYPE /etc/sysconfig/bootloader
to find out which boot loader is configured. If it is lilo, then you
must run the lilo command as root. If grub is listed, then your system
does not require any bootloader initialization.
Warning: An improperly installed bootloader may render your system
unbootable.
**** Step 6: reboot
If all of the steps above have been successfully completed on your
system, then the new kernel including the kernel modules and the
initrd should be ready to boot. The system needs to be rebooted for
the changes to become active. Please make sure that all steps have
completed, then reboot using the command
shutdown -r now
or
init 6
Your system should now shut down and reboot with the new kernel.
4) package location and checksums
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

6) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum
after you downloaded the file from a SUSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key security@suse.de),
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig
to verify the signature of the package, where is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SUSE Linux distributions version 7.1 and thereafter install the
key "build@suse.de" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
