To neutralize this exposure, follow the steps in the Recommended Solutions part of this bulletin. It is HIGHLY RECOMMENDED that these measures be implemented on ALL SGI systems running IRIX 5.2, 5.3, 6.0, 6.0.1, 6.1. This issue has been corrected for future releases of IRIX. ______________________________________________________________________ Silicon Graphics will not be liable for any consequential damages arising from the use of, or failure to use or use properly, any of the instructions or information in this Security Advisory. ______________________________________________________________________ BACKGROUND: To determine if the packaging system is installed on a particular system, the following command can be used: % versions eoe2.sw.oampkg | grep oampkg I eoe2.sw.oampkg 03/25/94 ATT Packaging Utility % In the above case, the packaging system is installed and the steps below, under Recommended Solutions, should be performed. If no output is returned by the command, the subsystem is not installed and no further action is required. IMPACT: The "ATT Packaging Utility" (eoe2.sw.oampkg) subsystem is not installed as part of the standard IRIX operating system. It is optionally installed when manually selected to be installed when using the IRIX inst program. Therefore, not all SGI systems will have this subsystem installed. For those systems in which the subsystem is installed, both local and remote users may be able to overwrite files and/or become root on a targeted SGI system. RECOMMENDED SOLUTIONS: *IF* the packaging subsystem is installed, the following steps can be used to neutralize the exposure by changing permissions on select programs of the eoe2.sw.oampkg subsystem. There is no patch for this issue. 1) Become the root user on your system. % /bin/su Password: # 2) Change the permissions on the following programs. # /sbin/chmod 755 /usr/pkg/bin/pkgadjust # /sbin/chmod 755 /usr/pkg/bin/abspat 3) Return to the previous user state. # exit % <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> ASSIST would like to thank SGI for information included in this bulletin. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> ASSIST is an element of the Defense Information Systems Agency (DISA), and provides service to the entire DoD community.
