No updates for k_*_22? I have patched my 7.1 box myself now but you do ship it with all 7.x versions including Enterprise server and I may not be the only one using that. Regards Hubba On Tue, 25 Mar 2003, Roman Drahtmueller wrote:

1) problem description, brief discussion, solution, upgrade information

The Linux kernel has a security flaw in all versions used on SuSE products excluding the upcoming SuSE Linux 8.2 distribution. The flaw is known as ptrace/modprobe bug: The local attacker can use ptrace and attach to a modprobe process that is spawned if the user triggers the loading of a kernel module using the kmod kernel module subsystem. This can be done by asking for network protocols that are supplied by kernel modules which are not loaded (yet). The vulnerability allows the attacker to execute arbitrary commands as root.

There exists a temporary workaround against this flaw: It is possible to temporaryly disable the kmod kernel module loading subsystem in the kernel after all necessary kernel modules have been loaded (Note: SuSE systems do not unload kernel modules in regular intervals.). If the temporary workaround is chosen, it should be made sure that no additional kernel modules need to be loaded afterwards (such as ISDN drivers, scsi subsystem drivers or filesystem drivers such as the iso9660 filesystem for cdroms and the language codepages). To disable the kmod kernel module loading subsystem, use the following command as root:

echo /no/such_file > /proc/sys/kernel/modprobe

If this command is inserted into a boot script that runs after all services in a runlevel have been launched, it is an efficient permanent solution. This workaround can be reverted by writing the original content ("/sbin/modprobe") back to the /proc/sys/kernel/modprobe file. Please note that it is still possible for the root user to manually load kernel modules.

As a permanent remedy for the problem we offer kernel update packages for download from our ftp server. Please follow the guidelines that are given in the extensive installation intructions below. The update should be performed with special care in order to make sure that the system will properly boot after the package update.

Note: Managing the necessary patches, building and mostly testing kernel update packages is an extremely worksome and therefore also time-consuming process. SuSE wishes to provide the same quality and reliability in update packages as customers are used to from the shipped original products. Even though our kernel updates are thoroughly tested, the numerous possible hardware configurations for the x86 platform give a certain probability for a functional failure of parts of the kernel after the update has been performed. Some of the possible failures cannot be handled by SuSE by definition. These include (and are not limited to) possible problems with NVIDIA chipset graphics boards that make use of hardware 3D acceleration. SuSE cannot deliver the binary only driver for the NVIDIA graphics boards in the kernel RPM. The kernel of a Linux system is the most critical component with respect to stability, reliability and security. By consequence, an update of that component requires some care and full attention to succeed. If you do not run a system where multiple users have access to, you may want to consinder to not perform this update since the security risk imposed by this bug is very small on a system with only one user.

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, you decide if the paragraph is needed for you or not. Please read through all of the steps down to the end. 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 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

The following options are possible (disregarding the version and build number following the name, seperated by the "-" character):

k_deflt # default kernel, good for most systems. k_i386 # kernel for older processors and chipsets k_athlon # kernel made specifically for AMD Athlon family processors k_orig # kernel built with unmodified sources k_psmp # kernel for Pentium-I dual processor systems k_smp # kernel for SMP systems (Pentium-II and above)

**** Step 2: Download the package for your system

Please download the kernel RPM package for your distribution with the name starting as indicated by Step 1. The list of all kernel rpm packages is appended below. Note: The kernel-source package does not contain any binary kernel in bootable form. Instead, it contains the sources that the binary kernel rpm packages are made 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.

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 applied.

**** Step 4: configuring and creating the initrd

The initrd is a ramdisk that is being 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 (set in the files /etc/rc.config up to 7.3) or /etc/sysconfig/kernel (after and including 8.0)) 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 rmadisk (initrd) for your system.

**** Step 5: bootloader

If you have a 7.x system, you must now run the command

lilo

as root to initialize the lilo bootloader for your system. Then proceed to the next step.

If you run a SuSE Linux 8.x or a SLES8 system, there are two options: Depending on your software configuration, you have 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 applied to 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 are complete, then reboot using the command shutdown -r now or init 6

Your system should now shut down and reboot with the new kernel.

3) 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 .

Hi, Roman! No offence, but I think you'll have to pay more attention when you compile the kernel upgrade... for instance, in the upgrade 2.4.18 for SuSE 8.1, you use modules from 2.4.19... and no machine will start... NEVER EVER... I allready put 2.4.19 over your upgrade to 2.4.18 in order to solve this issue!!! The issue is that both machines was remote servers of pretty important clients... and I have to go to them... and so on... Regards, Radu ----- Original Message ----- From: "Roman Drahtmueller" To: Sent: Tuesday, March 25, 2003 7:30 PM Subject: [suse-security] SuSE Security Announcement: kernel (SuSE-SA:2003:021) -----BEGIN PGP SIGNED MESSAGE----- ____________________________________________________________________________ __ SuSE Security Announcement Package: kernel Announcement-ID: SuSE-SA:2003:021 Date: Tuesday, Mar 25 2003 18:00 MET Affected products: 7.1, 7.2, 7.3, 8.0, 8.1 SuSE Linux Database Server, SuSE eMail Server III, 3.1 SuSE Linux Enterprise Server 7, SuSE Linux Enterprise Server 8, SuSE Linux Firewall on CD/Admin host SuSE Linux Connectivity Server SuSE Linux Office Server Vulnerability Type: local privilege escalation Severity (1-10): 6 SuSE default package: yes Cross References: CAN-2003-0127 Content of this advisory: 1) security vulnerability resolved: kernel problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - none in this security announcement 3) standard appendix (further information) ____________________________________________________________________________ __ 1) problem description, brief discussion, solution, upgrade information The Linux kernel has a security flaw in all versions used on SuSE products excluding the upcoming SuSE Linux 8.2 distribution. The flaw is known as ptrace/modprobe bug: The local attacker can use ptrace and attach to a modprobe process that is spawned if the user triggers the loading of a kernel module using the kmod kernel module subsystem. This can be done by asking for network protocols that are supplied by kernel modules which are not loaded (yet). The vulnerability allows the attacker to execute arbitrary commands as root. There exists a temporary workaround against this flaw: It is possible to temporaryly disable the kmod kernel module loading subsystem in the kernel after all necessary kernel modules have been loaded (Note: SuSE systems do not unload kernel modules in regular intervals.). If the temporary workaround is chosen, it should be made sure that no additional kernel modules need to be loaded afterwards (such as ISDN drivers, scsi subsystem drivers or filesystem drivers such as the iso9660 filesystem for cdroms and the language codepages). To disable the kmod kernel module loading subsystem, use the following command as root: echo /no/such_file > /proc/sys/kernel/modprobe If this command is inserted into a boot script that runs after all services in a runlevel have been launched, it is an efficient permanent solution. This workaround can be reverted by writing the original content ("/sbin/modprobe") back to the /proc/sys/kernel/modprobe file. Please note that it is still possible for the root user to manually load kernel modules. As a permanent remedy for the problem we offer kernel update packages for download from our ftp server. Please follow the guidelines that are given in the extensive installation intructions below. The update should be performed with special care in order to make sure that the system will properly boot after the package update. Note: Managing the necessary patches, building and mostly testing kernel update packages is an extremely worksome and therefore also time-consuming process. SuSE wishes to provide the same quality and reliability in update packages as customers are used to from the shipped original products. Even though our kernel updates are thoroughly tested, the numerous possible hardware configurations for the x86 platform give a certain probability for a functional failure of parts of the kernel after the update has been performed. Some of the possible failures cannot be handled by SuSE by definition. These include (and are not limited to) possible problems with NVIDIA chipset graphics boards that make use of hardware 3D acceleration. SuSE cannot deliver the binary only driver for the NVIDIA graphics boards in the kernel RPM. The kernel of a Linux system is the most critical component with respect to stability, reliability and security. By consequence, an update of that component requires some care and full attention to succeed. If you do not run a system where multiple users have access to, you may want to consinder to not perform this update since the security risk imposed by this bug is very small on a system with only one user. 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, you decide if the paragraph is needed for you or not. Please read through all of the steps down to the end. 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 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 The following options are possible (disregarding the version and build number following the name, seperated by the "-" character): k_deflt # default kernel, good for most systems. k_i386 # kernel for older processors and chipsets k_athlon # kernel made specifically for AMD Athlon family processors k_orig # kernel built with unmodified sources k_psmp # kernel for Pentium-I dual processor systems k_smp # kernel for SMP systems (Pentium-II and above) **** Step 2: Download the package for your system Please download the kernel RPM package for your distribution with the name starting as indicated by Step 1. The list of all kernel rpm packages is appended below. Note: The kernel-source package does not contain any binary kernel in bootable form. Instead, it contains the sources that the binary kernel rpm packages are made 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. 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 applied. **** Step 4: configuring and creating the initrd The initrd is a ramdisk that is being 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 (set in the files /etc/rc.config up to 7.3) or /etc/sysconfig/kernel (after and including 8.0)) 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 rmadisk (initrd) for your system. **** Step 5: bootloader If you have a 7.x system, you must now run the command lilo as root to initialize the lilo bootloader for your system. Then proceed to the next step. If you run a SuSE Linux 8.x or a SLES8 system, there are two options: Depending on your software configuration, you have 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 applied to 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 are complete, then reboot using the command shutdown -r now or init 6 Your system should now shut down and reboot with the new kernel.

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.
