-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: mysql Announcement-ID: SuSE-SA:2003:003 Date: Thu Jan 2 15:00:00 MET 2003 Affected products: 7.1, 7.2, 7.3, 8.0, 8.1, SuSE Linux Enterprise Server 7, SuSE Linux Enterprise Server 8, SuSE Linux Connectivity Server, SuSE Linux Office Server, UnitedLinux 1.0 Vulnerability Type: remote command execution Severity (1-10): 6 SuSE default package: no Cross References: http://security.e-matters.de/advisories/042002.html Content of this advisory: 1) security vulnerability resolved: Signedness issue and password checking in mysqld, buffer overflow in mysqlclient library. problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: grub 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Stefan Esser from e-matters reported various bugs in MySQL. Within the MySQL server the password checking and a signedness issue has been fixed. These could lead to a remote compromise of the system running an unpatched MySQL server. In order to exploit this bug, the remote attacker needs a valid MySQL account. Further, a buffer overflow in the mysqlclient library has been reported and fixed. Applications using this library (as commonly used from within PHP scripts) are vulnerable to this attack and could also be compromised by remote attackers. Since there is no workaround possible except shutting down the MySQL server, we strongly recommend an update. 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. To be sure the update takes effect you have to restart the MySQL server by executing the following command as root: /etc/rc.d/mysql restart If you run applications which utilize the mysqlclient library (i.e. software that accesses a MySQL database server) make sure you restart them again to force the use of the patched libraries. We thank MySQL Product and Release Engineer Lenz Grimmer as well as e-matters Stefan Esser who discovered the bugs for their committment to security matters and the communication of them. i386 Intel

manager allows users with physical access to the terminal to circumvent the password protection from grub. Fixed packages will soon be available. ______________________________________________________________________________ 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@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@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.
