This attack is only possible with firewalling enabled.<br /><br />   We would like to thank Richard Hart for reporting the problem.<br /><br />   This problem has already been fixed in the 2.6.8 upstream Linux kernel,<br />   this update contains a backport of the fix.<br /><br />   Products running a 2.4 kernel are not affected.<br /><br />   Mitre has assigned the CVE ID CAN-2004-0816 for this problem.<br /><br /><br />   Additionaly Martin Schwidefsky of IBM found an incorrectly handled<br />   privileged instruction which can lead to a local user gaining<br />   root user privileges.<br /><br />   This only affects the SUSE Linux Enterprise Server 9 on the S/390<br />   platform and has been assigned CVE ID CAN-2004-0887.<br /><br /><br />   Additionaly the following non-security bugs were fixed:<br /><br />   - Two CD burning problems.<br /><br />   - USB 2.0 stability problems under high load on SMP systems.<br /><br />   - Several SUSE Linux Enterprise Server issues.<br />     (see the Maintenance Information Mail for more informations).<br /><br /><br />2) solution/workaround<br /><br />   If you are not using an iptables based firewall (like SUSEfirewall2)<br />   on your system, you are not affected.<br /><br />   If you are using a firewall, a workaround is to disable firewall<br />   logging of IP and TCP options.<br /><br />   We recommend to update the kernel.<br /><br />3) special instructions and notes<br /><br />    SPECIAL INSTALL INSTRUCTIONS:<br />    ==============================<br />    The following paragraphs will guide you through the installation<br />    process in a step-by-step fashion. The character sequence "****"<br />    marks the beginning of a new paragraph. In some cases, the steps<br />    outlined in a particular paragraph may or may not be applicable<br />    to your situation.<br />    Therefore, please make sure to read through all of the steps below<br />    before attempting any of these procedures.<br />    All of the commands that need to be executed are required to be<br />    run as the superuser (root). Each step relies on the steps before<br />    it to complete successfully.<br /><br /><br />  **** Step 1: Determine the needed kernel type<br /><br />    Please use the following command to find the kernel type that is<br />    installed on your system:<br /><br />      rpm -qf /boot/vmlinuz<br /><br />    Following are the possible kernel types (disregard the version and<br />    build number following the name separated by the "-" character)<br /><br />      kernel-64k-pagesize<br />      kernel-bigsmp<br />      kernel-default<br />      kernel-smp<br /><br />  **** Step 2: Download the package for your system<br /><br />    Please download the kernel RPM package for your distribution with the<br />    name as indicated by Step 1. The list of all kernel rpm packages is<br />    appended below. Note: The kernel-source package does not<br />    contain a binary kernel in bootable form. Instead, it contains the<br />    sources that the binary kernel rpm packages are created from. It can be<br />    used by administrators who have decided to build their own kernel.<br />    Since the kernel-source.rpm is an installable (compiled) package that<br />    contains sources for the linux kernel, it is not the source RPM for<br />    the kernel RPM binary packages.<br /><br />    The kernel RPM binary packages for the distributions can be found at the<br />    locations below ftp://ftp.suse.com/pub/suse/i386/update/.<br /><br />      9.1/rpm/i586<br /><br />    After downloading the kernel RPM package for your system, you should<br />    verify the authenticity of the kernel rpm package using the methods as<br />    listed in section 3) of each SUSE Security Announcement.<br /><br /><br />  **** Step 3: Installing your kernel rpm package<br /><br />    Install the rpm package that you have downloaded in Steps 3 or 4 with<br />    the command<br />        rpm -Uhv --nodeps --force <K_FILE.RPM><br />    where <K_FILE.RPM> is the name of the rpm package that you downloaded.<br /><br />    Warning: After performing this step, your system will likely not be<br />             able to boot if the following steps have not been fully<br />             followed.<br /><br /><br />  **** Step 4: configuring and creating the initrd<br /><br />    The initrd is a ramdisk that is loaded into the memory of your<br />    system together with the kernel boot image by the bootloader. The<br />    kernel uses the content of this ramdisk to execute commands that must<br />    be run before the kernel can mount its actual root filesystem. It is<br />    usually used to initialize SCSI drivers or NIC drivers for diskless<br />    operation.<br /><br />    The variable INITRD_MODULES in /etc/sysconfig/kernel determines<br />    which kernel modules will be loaded in the initrd before the kernel<br />    has mounted its actual root filesystem. The variable should contain<br />    your SCSI adapter (if any) or filesystem driver modules.<br /><br />    With the installation of the new kernel, the initrd has to be<br />    re-packed with the update kernel modules. Please run the command<br /><br />      mk_initrd<br /><br />    as root to create a new init ramdisk (initrd) for your system.<br />    On SuSE Linux 8.1 and later, this is done automatically when the<br />    RPM is installed.<br /><br /><br />  **** Step 5: bootloader<br /><br />    If you run a SUSE LINUX 8.x, SLES8, or SUSE LINUX 9.x system, there<br />    are two options:<br />    Depending on your software configuration, you have either the lilo<br />    bootloader or the grub bootloader installed and initialized on your<br />    system.<br />    The grub bootloader does not require any further actions to be<br />    performed after the new kernel images have been moved in place by the<br />    rpm Update command.<br />    If you have a lilo bootloader installed and initialized, then the lilo<br />    program must be run as root. Use the command<br /><br />      grep LOADER_TYPE /etc/sysconfig/bootloader<br /><br />    to find out which boot loader is configured. If it is lilo, then you<br />    must run the lilo command as root. If grub is listed, then your system<br />    does not require any bootloader initialization.<br /><br />    Warning: An improperly installed bootloader may render your system<br />             unbootable.<br /><br />  **** Step 6: reboot<br /><br />    If all of the steps above have been successfully completed on your<br />    system, then the new kernel including the kernel modules and the<br />    initrd should be ready to boot.

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