Package: kdelibs/kdelibs3 Announcement-ID: SuSE-SA:2003:014 Date: Wed May 26 12:00:00 MEST 2004 Affected products: 8.0, 8.1, 8.2, 9.0, 9.1 SuSE Linux Database Server, SuSE Linux Enterprise Server 7, 8 SuSE Linux Firewall on CD 2 SuSE Linux Connectivity Server SuSE Linux Office Server SuSE Linux Desktop 1.0 Vulnerability Type: remote file creation Severity (1-10): 6 SUSE default package: yes Cross References: CAN-2004-0411

Content of this advisory: 1) security vulnerability resolved: URI file creation vulnerability problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - rsync - film - apache/mod_ssl 3) standard appendix (further information)

______________________________________________________________________________

1) problem description, brief discussion, solution, upgrade information

The kdelibs3 (kdelibs for SLES7 based products) package is a core package for the K desktop environment (KDE). The URI handler of the kdelibs3 and kdelibs class library contains a flaw which allows remote attackers to create arbitrary files as the user utilizing the kdelibs3/kdelibs package. Affected are applications which use the kdelibs3/kdelibs URI handler such as Konqueror or Kmail. The original KDE advisory can be found at http://www.kde.org/info/security/advisory-20040517-1.txt

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.

2) Pending vulnerabilities in SUSE Distributions and Workarounds:

- rsync rsync prior to version 2.6.1 does not properly sanitize paths when running as read/write daemon without chroot. New update packages are available on our ftp servers which fix this problem.

- film The film program creates temporary files in an insecure way. New update packages are available on our ftp servers.

- apache/mod_ssl A buffer overflow in a uuencode function of mod_ssl has been fixed as well as various minor bugs (CAN-2003-0987, CAN-2003-0020, CAN-2004-0174 and CAN-2003-0993). New packages are currently being tested and will soon be available on our ftp servers.

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 .
