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: Super 3.11.7 is available at: ftp.ucolick.org:/pub/users/will/super-3.11.7.tar.gz The new version of Super will be available soon on the mirror: ftp.onshore.com:/pub/mirror/software/super Please refer to these locations for fixes which are 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 immediately. 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.
