-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: sendmail Announcement-ID: SuSE-SA:2003:035 Date: Tuesday, Aug 26th 2003 19:00 MEST Affected products: 8.0, 8.1, 8.2 SuSE Linux Enterprise Server 8 remote denial-of-service Severity (1-10): 5 SuSE default package: no Cross References: CAN-2003-0688 Content of this advisory: 1) security vulnerability resolved: calling free() with arbitrary argument problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - traceroute(-nanog) - gdm2 - pam_smb - exim 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The well known and widely used MTA sendmail is vulnerable to a remote denial-of-service attack in version 8.12.8 and earlier (but not before 8.12). The bug exists in the DNS map code. This feature is enabled by specifying FEATURE(`enhdnsbl'). When sendmail receives an invalid DNS response it tries to call free(3) on random data which results in a process crash. After your system was updated you have to restart your sendmail daemon to make the update effective. There is no known workaround for this vulnerability other than using a different MTA. 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.

New packages are available on out FTP servers. - gdm2 Due to a bug in GDM it is possible for local users to read any text file on a system by creating a symlink from ~/.xsession-errors. Updated packages will be available on our FTP servers soon. - pam_smb A buffer overflow in the password handling function of pam_smb allows remote root compromise. Fixed packages will be available soon. - exim Two bugs where fixed in exim. One bug allows remote access as user mail/mail and the other one allows local root access for 'Admin Users'. Fixed packages are available on our FTP servers. ______________________________________________________________________________ 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 <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 security(a)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 <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 "build(a)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 . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

SuSE Security Announcement: kernel (SuSE-SA:2003:034)
by Sebastian Krahmer 12 Aug '03

12 Aug '03

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: kernel Announcement-ID: SuSE-SA:2003:034 Date: Tue Aug 12 18:15:00 CEST 2003 Affected products: 7.2, 7.3, 8.0, 8.1, 8.2 SuSE Linux Database Server, SuSE eMail Server III, 3.1 SuSE Linux Enterprise Server 7, 8 SuSE Linux Firewall on CD/Admin host SuSE Linux Connectivity Server SuSE Linux Office Server SuSE Linux Openexchange Server SuSE Linux Desktop 1.0 United Linux 1.0 Vulnerability Type: local privilege escalation, remote Denial of Service (DoS) Severity (1-10): 7 SuSE default package: yes Cross References: CAN-2003-0476 CAN-2003-0501 CAN-2003-0464 Content of this advisory: 1) security vulnerability resolved: a race condition in the ELF loader, a minor information leakage problem in the proc-fs, re-binding problem of UDP port 2049 sockets, DoS in netfilter and NFSv3 code 2) pending vulnerabilities, solutions, workarounds: - xfstt - heartbeat - KDE config files - several minor bug fixes 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information During the last weeks a couple of security relevant fixes have been accumulated for the kernel. These fix local vulnerabilities and remote DoS conditions. The list of the fixed vulnerabilities is as follows: - fix for a possible denial of service attack (DoS) in the routing code - fix for a possible attack of an unpriviledged user via ioport - fix for a re-binding problem of UDP port 2049 (NFS) sockets - fix for a kernel panic with pptpd when mss > mtu - fix for console redirect bug - fix for the execve() file read race vulnerability - fix for several race conditions in procfs - fix for possible DoS in netfilter code - fix for possible DoS in NFSv3 code Not all kernel-versions are affected by all of these vulnerabilities. However, since there is no easy workaround for all of the vulnerabilities, we recommend an update of the kernel package. Please follow the steps in the "SPECIAL INSTALL INSTRUCTIONS" section to update your system. 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. It is known that the NVIDIA hardware acceleration will not continue to work after a reboot, resulting in a failure to start the X-server. Hardware acceleration support for NVIDIA graphics chipsets on SuSE Linux 8.1 and 8.2 will be automatically disabled if the kernel update is performed by YOU (Yast Online Update). If you are committing the update by hand (necessary for SuSE Linux 8.0 and older), you should either turn off hardware acceleration support for your X Server configuration, or you may want to link the acceleration driver with binaries directly from nvidia's ftp server yourself, using the provided kernel-source RPM package. 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. 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, separated 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(tm) family processors 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. The kernel RPM binary packages for the distributions can be found at these locations under ftp://ftp.suse.com/pub/suse/i386/update/ : 7.2/kernel/2.4.18-20030812 7.3/kernel/2.4.18-20030812 8.0/kernel/2.4.18-20030812 8.1/rpm/i586 8.2/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 applied. If you run SuSE Linux 8.1 and use 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 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. Download sources for all kernel RPM packages: Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. Due to the large amount of package-names you will not find the usual list of package-names with the corresponding MD5 sums here. However the integrity of the packages is ensured and can be verified as described in section 3.2. ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - xfstt The X truetype font-server can be crashed my sending malicious packets over the network. It may even be possible to execute arbitrary commands with the privileges of the xfstt server. Update packages are available on our FTP servers now. - heartbeat New heartbeat packages which fix an overflow are available on our ftp servers. - KDE config files Due to an mistake some files in /etc/opt/kde3/share/config/ of SuSe Linux 8.2 are world-writeable. Under certain circumstances these files can be used to gain higher privileges. Please add an entry for each file in your /etc/permissions.local file. Example: /etc/opt/kde3/share/config/kmailrc root.root 0644 This bug was reported by nordi <nordi(a)addcom.de>. - several minor bug fixes There are alot more minor security updates in the queue. YOU (Yast Online Update) will inform you when they appear. Alternatively you may want to monitor the following website: http://www.suse.de/de/private/download/updates/index.html or: http://www.suse.de/en/private/download/updates/index.html ______________________________________________________________________________ 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 <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 security(a)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 <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 "build(a)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 . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

SuSE Linux Enterprise Server 8 gets Common Criteria Certificate
by Roman Drahtmueller 05 Aug '03

05 Aug '03

-----BEGIN PGP SIGNED MESSAGE----- This non-standard SuSE Security Announcement does not provide any details about security incidents and is posted to suse-security-announce(a)suse.com for your information. Read the full press release about the successful Common Criteria Certification of the SuSE Linux Enterprise Server 8 below. The SuSE Security website has been redesigned. To read more about the certification (such as the Security Target), please direct your browser to http://www.suse.de/security/ ============================================================================= IBM and SuSE Linux Earn First Security Certification of Linux ARMONK, N.Y. and Oakland, CA, August 5, 2003 -- IBM and SuSE Linux today announced that the two companies have achieved the first ever security certification of Linux, taking the critical next step in the maturation of Linux and enabling the adoption of Linux by governments and companies around the world for mission critical environments. IBM and SuSE Linux have achieved Common Criteria Security Certification for SuSE Linux Enterprise Server 8 running on IBM eServer xSeries. The Common Criteria (CC) is an internationally recognized ISO standard (ISO 15408) used by the Federal government and other organizations to assess security and assurance of technology products. The CC provides a standardized way of expressing security requirements and defines the respective set of rigorous criteria by which the product will be evaluated. It is widely recognized among IT professionals, government agencies, and customers as a seal of approval for mission-critical software. "We are pleased that Linux has reached this important security milestone through the joint efforts of IBM and SuSE," said Fritz Schulz, Defense Information Systems Agency. "The Common Criteria certification of Linux will be a critical factor as Linux is applied to mission critical environments." SuSE Linux Enterprise Server 8 on IBM eServer xSeries has earned an Evaluation Assurance Level 2+ certification, commonly referred to as EAL2. IBM and SuSE also announced today that the companies have filed for a higher level of security certification for Linux, the Controlled Access Protection Profile with EAL3+ across the IBM eServer product line, which is expected later this year. In addition to the Common Criteria certification, SLES 8 on IBM eServer platforms will meet the Common Operating Environment (COE) standard later this year. This will lead to a product that simultaneously meets Common Criteria and COE requirements. This standard, unique to the US Department of Defense (DoD), addresses functionality and interoperability requirements for commercially acquired IT products. The COE specification is used to verify the look and feel and function of software products as they are joined with government customized code. The COE is broadly recognized as a standard computing environment across the U.S. Government command and control systems. "IBM and SuSE's landmark decision to submit the SuSE Linux Enterprise Server product to Common Criteria testing challenges the view of many skeptics that open source systems could not withstand such testing due to the difficulty of establishing processes in an open-source environment. This announcement demonstrates IBM's commitment to enterprise infrastructure that is secure, cost effective and open," said IBM Senior Vice President of Technology and Manufacturing, Nicholas Donofrio. "With this announcement, we continue to build upon our commitment to delivering Common Criteria certification across the IBM eServer platforms. Most importantly, the Common Criteria certification further validates the security and quality of open source software, not only for Global Government, but for other industries with critical security requirements." "SuSE is the world's only open source operating system manufacturer which has technically demonstrated Common Criteria proficiency that can control and minimize security risks through a comprehensive quality assurance process," said Richard Seibt, Chief Executive Officer, SuSE Linux. "The Common Criteria evaluation marks yet another first for SuSE, and will further reassure companies of the high quality and security of the SuSE Linux Enterprise Server." Sponsored by IBM, the evaluation was completed by atsec information security GmbH, one of the world's leading vendor-independent IT security consulting companies, accredited in Germany by the Federal Office for Information Security (BSI). Under Common Criteria, products are evaluated against strict standards for various features, such as the development environment, security functionality, the handling of security vulnerabilities, security related documentation and product testing. In certifying SLES 8 on IBM xSeries, atsec information security GmbH evaluated how SuSE Linux develops, tests and maintains its products, as well as assessing the processes in place at the company for handling security issues in its software. IBM and SuSE have committed to release key components of the Common Criteria evaluation to the CCeLinux Consortium and Linux development community, by the end of the month. In addition, IBM and SuSE will continue to work with the open source development community to actively enhance Linux security to make Linux even more secure than it is today. "We congratulate IBM and SuSE for their commitment to information security as evidenced by the recent successful evaluation and certification of SuSE Linux Enterprise Server 8. This Linux server product joins a growing list of commercial products evaluated under the international security standard Common Criteria---providing greater assurance in the component products used to build more secure information systems for the federal government," said Ron S. Ross, Ph.D., National Institute of Standards and Technology. In addition to IBM's ongoing commitment to accelerate the development and certification of Linux as a secure, industrial strength operating system, IBM will continue to invest in ongoing certifications for new and existing IBM products. Common Criteria certification is anticipated for IBM's premier virtualization technology, z/VM, in the upcoming year. z/VM allows mainframe customers to run tens to hundreds of instances of the Linux operating system on a single IBM zSeries server. IBM's suite of middleware products are also in line for Common Criteria certification on Linux. IBM Directory has just completed evaluation under the Common Criteria. WebSphere Application Server and Tivoli Access Manager are in evaluation today, and several other Software Group products are being prepared to enter the evaluation process.

Dear subscriber on suse-security-announce(a)suse.com, We at SuSE Security are pleased to see that security and privacy matters are being taken seriously particularly within the readership of suse-security-announce@. Also, the proscription of spam has started to show its effects already many months ago. We notice this every time after we have sent SuSE security announcements to the list. We receive more and more error messages that the announcement emails get rejected because * they were classified spam * an apparent virus has been detected in the content of the email * the gpg signature from the SuSE security team couldn't be verified or a combination of any. If you have received this mail, but you haven't received our SuSE Security Announcement about wuftpd (SuSE-SA:2003:032) from Thursday, July 31st 2003, you should contact your mail administrator to avoid security incidents that may occur because you have not received the SuSE Security Announcements. This should be the case for subscribers in some hundred internet domains. For obvious resons, this message is not crytographically signed as the SuSE Security Announcements are.

The most important ones are - NFSv3 remote DoS - netfilter DoS - /proc infoleak - race condition in the ELF loader These bugs are fixed. The new kernel packages will be approved as soon as the testing is finished. ______________________________________________________________________________ 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 <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 security(a)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 <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 "build(a)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 . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.
