-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: libtiff Announcement-ID: SUSE-SA:2004:038 Date: Friday, Oct 22nd 2004 18:00 MEST Affected products: 8.1, 8.2, 9.0, 9.1 SUSE Linux Enterprise Server 8, 9 SUSE Linux Desktop 1.0 Vulnerability Type: code execution Severity (1-10): 9 SUSE default package: yes Cross References: CAN-2004-0803 CAN-2004-0804 CAN-2004-0886 CAN-2004-0929 Content of this advisory: 1) security vulnerability resolved: - several buffer overflows and related problems in libtiff were fixed. problem description 2) solution/workaround 3) special instructions and notes 4) package location and checksums 5) pending vulnerabilities, solutions, workarounds: - security problems in PDF viewers - freeradius denial of service problems - mpg123 buffer overflow 6) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion libtiff is used by image viewers and web browser to view "TIFF" images. These usually open and display those images without querying the user, making a normal system by default vulnerable to exploits of image library bugs. Chris Evans found several security related problems during an audit of the image handling library libtiff, some related to buffer overflows, some related to integer overflows and similar. This issue is being tracked by the CVE ID CAN-2004-0803. Matthias Claasen found a division by zero in libtiff. This is tracked by the CVE ID CAN-2004-0804. Further auditing by Dmitry Levin exposed several additional integer overflows. These are tracked by the CVE ID CAN-2004-0886. Additionally, iDEFENSE Security located a buffer overflow in the OJPEG (old JPEG) handling in the SUSE libtiff package. This was fixed by disabling the old JPEG support and is tracked by the CVE ID CAN-2004-0929. SUSE wishes to thank all the reporters, auditors, and programmers for helping to fix these problems. 2) solution/workaround There is no workaround. Update the libtiff packages. 3) special instructions and notes Make sure that you restart your web browser after updating. 4) package location and checksums 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. You can also use the YaST Online Update tool to install the security updates. Our maintenance customers are being notified individually. The packages are being offered for installation from the maintenance web. x86 Platform: SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/libtiff-3.6.1-38.12.i5… cd373c181599ebbf3be0f021b811c7da patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/libtiff-3.6.1-38.12.i5… a45416ea1ac9628b9e4e7e6f09653cb5 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/tiff-3.6.1-38.12.src.rpm 2387abe21eebb97f319b6ddf1a982314 SUSE Linux 9.0: ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/libtiff-3.5.7-376.i586… db8b4d23eb887b3c391f5262f766ff86 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/libtiff-3.5.7-376.i586… 58112fc9e5c6395bc316f3b46ffeb0ca source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/src/tiff-3.5.7-376.src.rpm 0810ea6ffe77b7a450698386a6238e61 SUSE Linux 8.2: ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/libtiff-3.5.7-376.i586… 339e0ce21cceadb883d2022ec01c1219 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/libtiff-3.5.7-376.i586… 608c1b39e6d67c9da02e02d2176b7a97 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/src/tiff-3.5.7-376.src.rpm 8891d3c8ff0dd0f283f63d4b3021b894 SUSE Linux 8.1: ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/libtiff-3.5.7-376.i586… ______________________________________________________________________________ 5) Pending vulnerabilities in SUSE Distributions and Workarounds: - security problems in pdf viewers Chris Evans, Dmitry Levin and others found several buffer and integer overflow problems in xpdf and xpdf clones. These are being tracked under the CVE Ids CAN-2004-0888 and CAN-2004-0889. New packages will be available soon. - freeradius Several bugs that can be abused to remotely crash freeradius have been discovered (CAN-2004-0938, CAN-2004-0960, CAN-2004-0961). New packages will be available soon. - mpg123 A buffer overflow in mpg123 has been discovered. New packages will be available soon. ______________________________________________________________________________ 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 security(a)suse.de) the checksums show proof of the authenticity of the package. We recommend against subscribing to security lists that cause the e-mail 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 file name of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled 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.

Agreed again, I'm no geek, though I need to know what happens "behind the scenes" of a computer & Linux forces you to learn that. Even the Linux geeks in my working environment, my mentors & teachers, state how complicated playing with IPTables is. IP tables for dummies is just my level. I need a firewall sure 'nuff but it shouldn't take a month of sundays to build one.

It is not the reason because I saw a portscan, it is the reason, that the portscanner does as if he was probing kind'a' open proxies and whatever as his reason for doing portscans but not showing or telling what he exactly does.

It has a VERY nice graphical interface and can generate rules for a variety of platforms (including iptables). It stores the rules and objects in a platform independent fashion which unfortunitely means you can't just read in your old ruleset but once you've built your new one you could easily change your firewall platform (i.e. from Linux to some form of BSD) and just re-compile the rules for whichever system you need! The Linux/etc versions are free to use. The Windows version isn't free. Check out http://www.fwbuilder.org/ I've just built rules for our new firewall with 5 network interfaces with no trouble.

Just found this in freshmeat daily news. http://www.links2world.org/doc/links2world-Firewall-HOWTO/index.html Still in development. Taken from the homepage: links2world Firewall is a very simple tool writen in C, that helps you generate iptables rules for Linux 2.4.x and newer kernels. Released under GNU General Public License, it is very easy to configure and designed to run on hosts with one or more network interfaces. Most of the existing iptables script generators are shell scripts. You have to dig in and to look through entire script in order to customize and configure it for your needs. Furthermore, they are able to generate iptables rules for one or maximum two network interfaces. On the other hand, links2world Firewall uses a very human readable configuration file that is very easy to understand and write. Still more, it does not matter if you have one, two, three or twenty network interfaces, links2world Firewall is able to generate statefull iptables rulesets able to control the packet flows between all the networks your machine is connected to. May be of interest to anyone managing alot several NIC IF's.

SuSE Security Announcement: kernel (SUSE-SA:2004:037)
by Marcus Meissner 21 Oct '04

21 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement-ID: SUSE-SA:2004:037 Date: Wednesday, Oct 20th 2004 18:00 MEST Affected products: 9.1 SUSE Linux Enterprise Server 9 Vulnerability Type: remote denial of service Severity (1-10): 9 SUSE default package: yes Cross References: CAN-2004-0816 CAN-2004-0887 Content of this advisory: 1) security vulnerability resolved: - remote system crash with enabled firewall - local root exploit on the S/390 platform - minor /proc information leaks problem description 2) solution/workaround 3) special instructions and notes 4) package location and checksums 5) pending vulnerabilities, solutions, workarounds: - libtiff - cyrus-sasl - php4 - zinf ______________________________________________________________________________ 1) problem description, brief discussion An integer underflow problem in the iptables firewall logging rules can allow a remote attacker to crash the machine by using a handcrafted IP packet. This attack is only possible with firewalling enabled. We would like to thank Richard Hart for reporting the problem. This problem has already been fixed in the 2.6.8 upstream Linux kernel, this update contains a backport of the fix. Products running a 2.4 kernel are not affected. Mitre has assigned the CVE ID CAN-2004-0816 for this problem. Additionaly Martin Schwidefsky of IBM found an incorrectly handled privileged instruction which can lead to a local user gaining root user privileges. This only affects the SUSE Linux Enterprise Server 9 on the S/390 platform and has been assigned CVE ID CAN-2004-0887. Additionaly the following non-security bugs were fixed: - Two CD burning problems. - USB 2.0 stability problems under high load on SMP systems. - Several SUSE Linux Enterprise Server issues. (see the Maintenance Information Mail for more informations). 2) solution/workaround If you are not using an iptables based firewall (like SUSEfirewall2) on your system, you are not affected. If you are using a firewall, a workaround is to disable firewall logging of IP and TCP options. We recommend to update the kernel. 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) 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/. 9.1/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. **** 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. x86 Platform: SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/kernel-default-2.6.5-7… 735f99730442772d0caeb1043576da0e ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/kernel-smp-2.6.5-7.111… 8e38495a90203fdeef0167126e9699fd ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/kernel-bigsmp-2.6.5-7.… 54474a313ff90c5a5ded8cd3590016ee source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/kernel-default-2.6.5-7.… 60a46f48bbae6989a50d2b3c735cd176 ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/kernel-smp-2.6.5-7.111.… 5bc77692dc82521b83378c97d39acd72 ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/kernel-bigsmp-2.6.5-7.1… 348c5d63b8c26c548d8b5bfcc894b805 x86-64 Platform: SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/kernel-default-2.6… 53ec1285f8933f79b6e53f2cb4d2094a ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/kernel-smp-2.6.5-7… de3bf18c94d26a2b3477cf11cf723380 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/kernel-default-2.6.5-… 3e6123bd50f2802cf6a96ccfa2af674f ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/kernel-smp-2.6.5-7.11… 365354d9e91032e53436f949da6ae8f6 ______________________________________________________________________________ 5) Pending vulnerabilities in SUSE Distributions and Workarounds: libtiff - Several buffer and integer overflows have been found in the image handling library libtiff by Chris Evans and Dmitry Levin, recorded under CVE Ids: CAN-2004-0803,CAN-2004-0804,CAN-2004-0886. We are working on updates and will release them within the next days. cyrus-sasl - The SASL_PATH environment variable was also used to load plugins even with setuid privileges set, which can lead to a local root privilege escalation. The default SUSE installation was not found to be affected by this problem, neithertheless we are in the process of releasing updates. The CVE ID for this issue is: CAN-2004-0884 php4 - File overwrite problems were identified in php4. We have released updates for this issue. However, due to problems with php4-recode in combination with php4-mysql we had to withdraw the update from YaST2 Online Update for some SUSE Linux versions. New packages will be available soon. zinf - A tempfile race condition in zinf / freeamp was fixed, packages are available. phpMyAdmin - A bug in phpMyAdmin that would allow users to execute arbitrary commands has been discovered. New packages will be available soon. mysql - Several bugs in mysql have been discovered. New packages will be available soon. libpng - The issues with libpng described in CAN-2004-0954 and CAN-2004-0955 where already fixed in the last libpng update. Fixed packages are therefore already available on our ftp server. ______________________________________________________________________________ 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 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.

IPTables Firewall script Generator
by suse＠karsites.net 20 Oct '04

20 Oct '04

Hi all. Just found this in freshmeat daily news. http://www.links2world.org/doc/links2world-Firewall-HOWTO/index.html Still in development. Taken from the homepage: links2world Firewall is a very simple tool writen in C, that helps you generate iptables rules for Linux 2.4.x and newer kernels. Released under GNU General Public License, it is very easy to configure and designed to run on hosts with one or more network interfaces. Most of the existing iptables script generators are shell scripts. You have to dig in and to look through entire script in order to customize and configure it for your needs. Furthermore, they are able to generate iptables rules for one or maximum two network interfaces. On the other hand, links2world Firewall uses a very human readable configuration file that is very easy to understand and write. Still more, it does not matter if you have one, two, three or twenty network interfaces, links2world Firewall is able to generate statefull iptables rulesets able to control the packet flows between all the networks your machine is connected to. May be of interest to anyone managing alot several NIC IF's. HTH - Keith Roberts

Configuring SuSE 9.1 as software router
by scshepard＠comcast.net 20 Oct '04

20 Oct '04

hi all, I'm trying to configure my 9.1 Professional server to act as a software router. In the future I want it to be a firewall/net/proxy server also, but I'm already stumped. Two network cards (eth0, eth1) hiding behind a cable modem (ie: 192.168.1.0/24, 196.168.2.0/24, original, no?). What is the basic "dummy" setup? And what commands for checking the configuration and errors? thanks in advance. /steve
