Wir geben diese Informationen unveraendert an Sie weiter. Durch einen Buffer Overflow ist ein lokaler Benutzer bei Einsatz des Administrationstool 'Super' in der Lage, Root-Privilegien zu erlangen. Betroffen sind von diese Schwachstelle allen mit Debian Linux vertriebenen Versionen bzw. die Versionen 3.9.6 bis 3.11.6. Es wird empfohlen, ein Update auf Version 3.11.7 durchzufuehren. Mit freundlichen Gruessen, Ruediger Riediger, DFN-CERT - -- Ruediger Riediger | mailto:riediger@cert.dfn.de DFN-CERT GmbH | http://www.cert.dfn.de/team/riediger/ Vogt-Koelln-Str. 30 | Phone: +49(40)42883-2262 D-22527 Hamburg | FAX: +49(40)42883-2241 Germany | PGP-Key: finger riediger@ftp.cert.dfn.de - -----BEGIN PGP SIGNED MESSAGE----- ISS Security Advisory February 15, 1999 Buffer Overflow in "Super" package in Debian Linux Synopsis: Internet Security Systems (ISS) X-Force has discovered a vulnerability in the system administration utility, "Super". Super is used by administrators to allow certain users to execute commands with root privileges. The vulnerability is distributed with Debian Linux. It may allow local attackers to compromise root access. Super is a GNU copylefted package that is distributed with recent Debian Linux distributions, but it can be installed and configured for many Unix variants. Affected versions: ISS X-Force has determined that version 3.9.6 through version 3.11.6 are vulnerable. All versions of Super distributed with Debian Linux are vulnerable. Execute the following command to determine version information: # /usr/bin/super -V Fix Information: The main distribution point for the Super package: ftp.ucolick.org:/pub/users/will/ Mirror: ftp.onshore.com:/pub/mirror/software/super super-3.11.7.tar.gz full source code for 3.11.7 super-3.11.6.patch1 patches overflow in 3.11.6 super-3.11.6-3.11.7 patch to change 3.11.6 to 3.11.7 Please refer to these locations for fixes which will be included in Super version 3.11.7. Description: Super is a utility that allows authorized users to execute commands with root privileges. It is intended to be an alternate to setuid scripts, which are inherently dangerous. A buffer overflow exists in Super that may allow attackers to take advantage of its setuid configuration to gain root access. Recommended Action: Version 3.11.7 should be installed as soon as it is available. Administrators should take care to disable setuid root utilities that are not used by regular users. To disable Super permanently, execute the following command as root to disable the setuid bit: # chmod 755 /usr/bin/super __________ Copyright (c) 1999 by Internet Security Systems, Inc.
