1) problem description, brief discussion
Linux kernel
Several vulnerabilities have been found and fixed in the Linux
kernel.
Paul Starzetz reported that the missing serialization in
unix_dgram_recvmsg() which was added to kernel 2.4.28 can
be used by a local attacker to gain elevated privileges (root
access). This issue is tracked by the Mitre CVE ID CAN-2004-1068.
Paul Starzetz and Georgi Guninski reported independently that bad
argument handling and bad integer arithmetics in the IPv4 sendmsg
handling of control messages could lead to a local attacker crashing
the machine.
This problem was fixed by Herbert Xu and is tracked by the Mitre
CVE ID CAN-2004-1016.
Georgi Guninski reported a memory leak in the IP option handling
of the IPv4 sendmsg call.
Paul Starzetz found bad handling in the kernel IGMP code, which
could lead to a local attacker being able to crash the machine.
This problem was fixed by Chris Wright and is tracked by the Mitre
CVE ID CAN-2004-1137.
Olaf Kirch found and fixed a problem in the RPC handling in the
kernel of SUSE Linux 9.1, 9.2, and SUSE Linux Enterprise Server 9
which could lead to a remote attacker crashing the machine.
A local denial of service problem in the aio_free_ring system call
could allow a local attacker to crash the machine.
A problem in the memory management handling of ELF executables could
lead to a local attacker crashing the machine with a handcrafted
ELF binary. (This is a VMA overlap problem and not related to
earlier ELF problems.)
A buffer overflow in the system call handling in the 32bit system
call emulation on AMD64 / Intel EM64T systems was fixed. It is not
thought to be exploitable.
A memory leak in the ip_conntrack_ftp firewalling module was fixed
in the 2.6 kernels.
Various UML security issues in the SUSE Linux 9.2 UML setup
were fixed.
Additionally some non-security bugs were fixed in the released
kernels:
SUSE Linux Enterprise Server 8 and SUSE Linux 8.1:
- A memory leak in addition / removal of SCSI target devices was
fixed.
- A race condition in SCSI I/O accounting which could lead to
erroneous reports on SCSI disk I/O was fixed.
- S390: Patches from IBM have been installed in the S/390
architecture, both for 32 and 64bit.
Refer to the maintenance information mail for the full change log.
- The "memfrac" and "lower_zone_reserve" kernel parameters had
no effect since they were used before kernel command line parsing.
- PowerPC: Missing synchronization that could lead to processes
hanging in signal delivery was added.
SUSE Linux Enterprise Server 9 and SUSE Linux 9.1:
- A vfree() was called with interrupts disabled in the SCSI generic
device handling, which could lead to a hanging machine.
- A race condition between a file unlink and umount could lead to a
machine crash.
- Fixed a small memory leak in bio_copy_user().
- cdrecord -scanbus could crash the kernel when using the "gdth" SCSI
driver.
- Allow reading from zero page (/dev/zero) using O_DIRECT/rawio.
- Fixed some LSB issues in the fcntl compatibility handling.
- The st (SCSI tape) driver did not pass on generic SCSI ioctl
commands to the SCSI mid layer.
SUSE Linux 9.2:
- The kernel installation routines did not call depmod for the modules
in the -nongpl RPMs, so they could not be loaded.
This lead to non working USB modem drivers and similar.
This problem was fixed.
- A Problem with mounting iPods over FireWire was fixed.
- A data corruption problem in the megaraid driver was fixed.
- A pageattr overflow condition in the memory subsystem
and missing TLB flush if multiple pages were passed were fixed.
- Allow reading from zeropage with O_DIRECT/rawio.
- Do not restart the system on ACPI events after power down.
(Make it no longer start on opening the lid of just shutdown
laptops for instance.)
- New memory imbalance handling handling by Andrea leading
to better Out Of Memory (OOM) handling was added.
2) solution/workaround
Please install the fixed packages, there is no workaround.
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/.
8.1/rpm/i586
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 <K_FILE.RPM>
where <K_FILE.RPM> 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.
If you run SUSE LINUX 8.1 and haven't applied the kernel update
(SUSE-SA:2003:034), AND you are using the freeswan package, you also
need to update the freeswan rpm as a dependency as offered
by YOU (YaST Online Update). The package can be downloaded from
ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/
**** 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.

5) Pending vulnerabilities in SUSE Distributions and Workarounds:
Please see our Security Summary Report.
- problem with smbfs in the previous kernel update
We received reports of smbfs being broken by our last kernel
update (released on Dec 1st, SUSE-SA:2004:042).
This apparently only affects the smbfs filesystem on 2.6 kernels,
so SUSE Linux 9.1, 9.2, SUSE Linux Enterprise Server 9 and Novell
Linux Desktop 9.
This problem is unfortunately not yet fixed in this security
update, we will be releasing fixed packages in the begin of next
year.
As workaround please change to use the cifs filesystem if
possible, which replaces smbfs in the 2.6 kernel series.

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 <name-of-the-file.rpm>
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 [email protected]),
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 <file.rpm>
to verify the signature of the package, where <file.rpm> 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 "[email protected]" 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 .
