______________________________________________________________________________ 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.i586.rpm cd373c181599ebbf3be0f021b811c7da patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/libtiff-3.6.1-38.12.i586.patch.rpm 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.rpm db8b4d23eb887b3c391f5262f766ff86 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/libtiff-3.5.7-376.i586.patch.rpm 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.rpm 339e0ce21cceadb883d2022ec01c1219 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/libtiff-3.5.7-376.i586.patch.rpm 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.rpm ______________________________________________________________________________ 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@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@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@suse.com - general/linux/SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe@suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info@suse.com> or <suse-security-faq@suse.com> respectively. ==================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>. The <security@suse.de> public key is listed below. ==================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way.
