This is tracked by the Mitre CVE ID CAN-2005-0397. Andrei Nigmatulin reported 4 problems in older versions of ImageMagick: - A bug was found in the way ImageMagick handles TIFF tags. It is possible that a TIFF image file with an invalid tag could cause ImageMagick to crash. This is tracked by the Mitre CVE ID CAN-2005-0759. Only ImageMagick version before version 6 are affected. - A bug was found in ImageMagick's TIFF decoder. It is possible that a specially crafted TIFF image file could cause ImageMagick to crash. This is tracked by the Mitre CVE ID CAN-2005-0760. Only ImageMagick version before version 6 are affected. - A bug was found in the way ImageMagick parses PSD files. It is possible that a specially crafted PSD file could cause ImageMagick to crash. This is tracked by the Mitre CVE ID CAN-2005-0761. Only ImageMagick version before version 6.1.8 are affected. - A heap overflow bug was found in ImageMagick's SGI parser. It is possible that an attacker could execute arbitrary code by tricking a user into opening a specially crafted SGI image file. This is tracked by the Mitre CVE ID CAN-2005-0762. Only ImageMagick version before version 6 are affected. 2) solution/workaround Please install the updated packages. 3) special instructions and notes None. 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.

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 . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SUSE security discussion.
