-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: libtiff/tiff Announcement-ID: SUSE-SA:2005:001 Date: Monday, Jan 10th 2005 11:30 MET Affected products: 8.1, 8.2, 9.0, 9.1, 9.2 SUSE Linux Desktop 1.0 SUSE Linux Enterprise Server 8, 9 Novell Linux Desktop 9 Vulnerability Type: remote system compromise Severity (1-10): 8 SUSE default package: yes Cross References: CAN-2004-1183 CAN-2004-1308 Content of this advisory: 1) security vulnerability resolved: - integer overflow - buffer overflow problem description 2) solution/workaround 3) special instructions and notes 4) package location and checksums 5) pending vulnerabilities, solutions, workarounds: 6) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion Libtiff supports reading, writing, and manipulating of TIFF image files. iDEFENSE reported an integer overflow in libtiff that can be exploited by specific TIFF images to trigger a heap-based buffer overflow afterwards. This bug can be used by external attackers to execute arbitrary code over the network by placing special image files on web-pages and alike. Additionally a buffer overflow in tiffdump was fixed. 2) solution/workaround There is no workaround known. 3) special instructions and notes It is needed that all processes using libtiff are restarted. If you use GUI applications please close your X/GDM/KDM session(s) and log in again. 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. Our maintenance customers are being notified individually. The packages are being offered for installation from the maintenance web. x86 Platform:     SUSE Linux 9.2:     ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/libtiff-3.6.1-47.4.i586.rpm

pending vulnerabilities in SUSE Distributions and Workarounds: Please read our next summary report for more information. ______________________________________________________________________________ 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 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 to verify the signature of the package, where 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.
