SPECIAL NOTE REGARDING SECURITY VULNERABILITY

This hot fix requires that your software must already be configured prior to installation. If no configuration directory exists at the time of installation, security updates built into this hot fix will not be completed, leaving your software in a vulnerable state.

IMPORTANT NOTES

1. Files delivered in this hot fix will be backed up during the installation process. However, it is good general practice to back up your system before applying updates to software.

2. You must have Administrator Privileges on your CLIENT or SERVER machine.

3. All currently active SAS sessions, daemons, spawners and servers must be terminated before applying this hot fix.

4. This hot fix should be installed using the same userid who performed the initial software installation.

5. CONFIGURATION: No automatic configuration scripting is included for this hot fix. If you have previously configured software installed, the SAS Deployment Manager may present a screen where you will see "Apply SAS Hot Fixes" and "Configure SAS Hot Fixes" options. On this screen, you must ensure that the "Configure SAS Hot Fix" option is *not* selected. If this option is automatically selected, please de-select it prior to proceeding with the SAS Deployment Manager Screens. Failure to do so could have unintended consequences when applying this hot fix.

INSTALLATION

The hot fix will be applied using the SAS Deployment Manager. By default, the SAS Deployment Manager will search in the <SASHOME>/InstallMisc/HotFixes/New directory for hot fixes to be applied, but will also prompt for a location if you have downloaded hot fixes to a different directory.

After downloading S48012pt.zip, follow the instructions for applying hot fixes in the SAS Deployment Wizard and SAS Deployment Manager 9.4: User's Guide.

Please review the CONFIGURATION Important Note above concerning proper selection of the "Configure SAS Hot Fix" option in the SAS Deployment Manager.

The hot fix installation process generates the log file

<!SASHOME>/InstallMisc/InstallLogs/IT_date-and-time-stamp.log

Postexec log files are created after the installation is completed and identifies the files that were added, backed up, changed and removed. These log files include the ‘member’ hot fix id in the name of the file and are also written to the <!SASHOME>/InstallMisc/InstallLogs directory. There is one postexec log for each ‘member’ hot fix applied (member hot fixes are listed at the top of these instructions).

IMPORTANT NOTE Regarding SSL/TLS:

If your SAS Web Server is configured for SSL/TLS, you will need to install the latest Java 7 Update. Please visit the Updates for Java 7 download page for the latest available updates.

POST-INSTALLATION INSTRUCTIONS

1. Navigate to <SASHome>/SASWebServer/9.4/hotfix

Restarting the Agent must be done by using the hq-agent script with the ‘restart’ option. The new Pivotal Web Server 6.2 resource should appear on the Auto-Discovery section. Select and click the Add Into Inventory link to add this new resource into inventory.

7. If your SAS Web Server is configured for SSL/TLS and also have any configured LASR Servers running on the system,you will need to apply the follow steps.

   1. Modify the \LevX\Web\WebServer\conf\extra\httpd-ssl.conf file.

      1. Replace the SSLProtocol directive:

         From

         SSLProtocol all -SSLv2 -SSLv3

         To

         SSLProtocol all

      2. Replace the SSLCipherSuite directive:

         From

         SSLCipherSuite ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM -SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES128 -SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:AES256-GCM-SHA384:AES128 -GCM-SHA256:AES256-SHA256:AES128-SHA256

         To

         SSLCipherSuite RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5

   2. Modify the \LevX\Web\WebAppServer\SASServerX_X\conf\server.xml file for each SAS Web App Server instances on every midtier machine.

      Remove the following two attributes inside <Connector> element in this server.xml:

      ciphers="TLS_ECDHE_ECDSA_W..................."
      sslEnabledProtocols="TLSv1,TLSv1.1,TLSv1.2"

   3. Restart web server and all web app servers.

IMPORTANT NOTES Regarding hot fix updates:

1. This hot fix will create a backup configuration directory under <SASConfig>/LevX/Web/WebServerBackup. If you manually changed any configuration settings for SAS Web Server, you must manually merge these settings back into the new web server configuration.

2. This hot fix updates the Apache httpd server from version 2.2 to version 2.4. Any manually configured changes for SAS Web Server related to Apache 2.2 will need to be updated to reflect Apache 2.4.

3. For SiteMinder configuration using the updated Apache version, please review information in SAS® 9.4 Intelligence Platform: Middle-Tier Administration Guide, Fourth Edition
   For the updated Apache version delivered in this hot fix, step 2 under "Configuring SAS Web Server for the Web Agent" should read as follows:
