INSTALLATION INSTRUCTIONS FOR HOT FIX 81BA28 ON ABI+ FOR INTEL ARCHITECTURE BEFORE DOWNLOADING: The hot fix 81BA28 addresses the security issue(s) in Release 8.1 (TS1M0) of Base SAS software on ABI+ for Intel Architecture as documented in SAS Note(s): SN-004201 Potential security exposure for sites that have installed the spawner programs (objspawn or sastcpd) which may be reviewed at: http://www.sas.com/service/techsup/unotes/SN/004/004201.html The hot fix package that is downloaded is in tar format. The name of the tar file is 81ba28ia.tar, and it contains the following files: * sastcpd.81ba28 the replacement executable containing the hot fix * 81ba28ia.aud a hot fix identifier file that will allow Technical Support to determine which fixes have been applied to a system * 81ba28ia.txt a copy of these installation instructions; this file is installed in !SASROOT/hotfix/doc IMPORTANT NOTE(S): 1. This hot fix may be applied to both Version 8 (TS M0) and Release 8.1 (TS1M0). AFTER DOWNLOADING: The following instructions describe the steps for installing the files listed above. In this example, the directory where Release 8.1 (TS1M0) is installed is: /usr/lib/sas8 STEP 1: Assuming the tar file is downloaded to the user's HOME directory, follow these procedures to install the package. $> cd /usr/lib/sas8 $> tar xf $HOME/81ba28ia.tar STEP 2: The tar command will extract the file sastcpd.81ba28 into the !SASROOT/utilities/bin directory. To replace the current sastcpd executable follow these steps (assuming you are still in the /usr/lib/sas8 directory). $> cd utilities/bin $> chown myuserid sastcpd [where myuserid is a non-root userid] $> chmod 755 sastcpd $> mv sastcpd sastcpd.TS1M0 $> mv sastcpd.81ba28 sastcpd STEP 3: Last, in order to authenticate a client’s identity and check the client’s authority to access resources, some setup is required by the root account. This setup changes the setuid permissions of files in !SASROOT/utilities/bin to root. This can be accomplished executing the following commands: $> su root $> cd !SASROOT/utilities/bin $> chown root sastcpd $> chmod 4755 sastcpd $> exit This completes the installation of hot fix 81BA28 on ABI+ for Intel Architecture.
