Security Advisory Title: IRIX df Buffer Overrun Vulnerability Title: AUSCERT Advisory AA-97.19 and CERT Advisory CA-97.21 Number: 19970505-02-PX Date: November 18, 1997 ______________________________________________________________________________ Silicon Graphics provides this information freely to the SGI user community for its consideration, interpretation, implementation and use. Silicon Graphics recommends that this information be acted upon as soon as possible. Silicon Graphics provides the information in this Security Advisory on an "AS-IS" basis only, and disclaims all warranties with respect thereto, express, implied or otherwise, including, without limitation, any warranty of merchantability or fitness for a particular purpose.

The df(1) program is setuid root and as part of normal usage accepts user arguments to operate. It has been determined that an appropriately crafted set of arguments could be input to the df(1) program allowing execution of arbitrary user commands with root privileges. This resulting buffer overflow condition is considered a security vulnerability. Silicon Graphics Inc. has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL SGI systems. This issue will be corrected in future releases of IRIX. - - - - -------------- - - - - --- Impact --- - - - - -------------- The df(1) program (/sbin/df) is installed on all IRIX systems by default. A local account is required in order to exploit this vulnerability. With a local account the vulnerability can be exploited both locally and remotely. This vulnerability can be utilized to execute commands with root privileges. This security issue has been publically disclosed and discussed in several public forums including the BUGTRAQ mailing list. Additionally, security advisories AUSCERT AA-97.19 and CERT CA-97.21 have been publically released on the issue. - - - - -------------------------- - - - - --- Temporary Solution --- - - - - -------------------------- Although patches are available for this issue, it is realized that there may be situations where installing the patches immediately may not be possible. The steps below can be used to remove the vulnerability by removing the permissions of the df program. 1) Become the root user on the system. % /bin/su - Password: # 2) Change the permissions on the df program. # /bin/chmod 500 /sbin/df ************ *** NOTE *** ************ Removing the setuid root permissions from the df program will prevent non-root users and applications from using the df program. 3) Return to previous level. # exit $ - - - - ---------------- - - - - --- Solution --- - - - - ---------------- OS Version Vulnerable?

These commands are run as the user using the at(1) program. In normal operation, the at(1) program runs as a setuid root privileged program inorder to perform its tasks. Unfortunately, a buffer overrun has been discovered in the at(1) program which could allow arbitrary commands to be run as the privileged user root. Silicon Graphics Inc. has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL SGI systems. This issue will be corrected in future releases of IRIX. - - - - -------------- - - - - --- Impact --- - - - - -------------- The at(1) program is installed on all Silicon Graphics IRIX systems by default. A local account is required in order to exploit this vulnerability both locally and remotely. This vulnerability can be utilized to execute commands with root privileges.

Security Advisory Title: IRIX syserr and permissions programs Number: 19971103-01-PX Date: November 18, 1997 ______________________________________________________________________________ Silicon Graphics provides this information freely to the SGI user community for its consideration, interpretation, implementation and use. Silicon Graphics recommends that this information be acted upon as soon as possible. Silicon Graphics provides the information in this Security Advisory on an "AS-IS" basis only, and disclaims all warranties with respect thereto, express, implied or otherwise, including, without limitation, any warranty of merchantability or fitness for a particular purpose.

Both these issues have been addressed together as one issue by Silicon Graphics. The first vulnerability involves the syserr program. The System Error Notification Broker (syserr) program is part of the Desktop System Monitor which monitors the system for user defined events and then provides notification and/or action when those events occur. As part of normal operation, the syserr program manipulates certain history and configuration files. A security issue was found in these file operations. The second issue involves the permissions tool found in the Indigo Magic Desktop environment. The permissions tool allows users to modify the Owner, Group and Others permission bits for files and directories. A security issue was found in the operation of the permissions tool. Silicon Graphics Inc. has investigated these issues and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL SGI systems. These issues will be corrected in future releases of IRIX. - - - - -------------- - - - - --- Impact --- - - - - -------------- The IndigoMagic Desktop and Desktop System Monitor subsystems, which contain the permissions and syserr programs respectively, are installed by default on all desktop systems. These subsystems may also be installed on other non-desktop systems. Both of these issues require a local account for these vulnerabilities to be exploited. With a local account, these vulnerabilities can be exploited both locally and remotely. Utilizing the syserr vulnerability, random files can be created and corrupted. With the permissions vulnerability, access can be gained as a privileged user. Both of these security issues have been publically disclosed and discussed in several public forums. - - - - -------------------------- - - - - --- Temporary Solution --- - - - - -------------------------- Although patches are available for this issue, it is realized that there may be situations where installing the patches immediately may not be possible. The steps below can be used to remove the vulnerability by removing the permissions of the syserr and permissions programs. 1) Become the root user on the system. % /bin/su - Password: # 2) Change the permissions on the programs. # /bin/chmod 500 /usr/sbin/syserr # /bin/chmod 500 /usr/lib/desktop/permissions ************ *** NOTE *** ************ Removing the permissions from these programs will prevent non-root users and programs from using these programs. 3) Return to previous level. # exit $ - - - - ---------------- - - - - --- Solution --- - - - - ---------------- OS Version Vulnerable?
