SNF Lab Members:

As you may know, there has been a lot of press in the last week about a 
"zero-day" exploit in Java that affects all computer platforms and all 
browsers that run on those platforms.  It was believed that this 
affected only Java 7 and not Java 6.  A number of you likely have Java 7 
on your machines.  Earlier today, Oracle has released an updated version 
of both Java 7 (specifically Java 7 update 7) and Java 6 (Java 6 update 
36) to address these issues.

If you run Remote Coral on a computer, you have either Java 6 or Java 7 
on your machine and should update those versions as soon as possible to 
reduce the likelihood that you machines will become infected or injected 
with various forms of malware.

For those of you running Windows XP or Windows 7, the easiest way to 
upgrade your machine is to open the Java Control Panel .  This is 
normally an icon on the main page that contains other control panels.  
That  will usually be found on either XP or Windows 7 machines in:

Windows XP Click Start > Settings > Control Panel

Windows 7, Windows Vista Click Start > Control Panel > Programs

Double click that Java icon which should open the Java Control Panel.  
There you should see the Update tab.

Select that and click the "Update Now" button.  That should download and 
install the latest version of the Java Runtime Environment (JRE) onto 
your machine.

After that is done, you may want to open the Java Control Panel again, 
but this time select the Java tab.  On that page you will see a "View 
..." button.  Clicking that will show you the version (or versions) of 
Java that are currently installed on your machine.  After the upgrade 
you should under Platform either 1.7 (Java 7) or 1.6 (Java 6) and under 
product it should list either 1.7.0_07 for the latest version of Java 7 
or 1.6.0_35 for the latest version of Java 6.

Note: if you run Stanford administrative application, you may also see 
Java 1.6.0_21 because a number of Stanford-specific applications will 
ONLY run on that version of Java.

In any event, I encourage you to make these upgrades as soon as possible 
to minimize the chances that undesirable code may get injected onto your 
machine.

Note: while I am less familiar with Mac OS-X, if you are running Java 7 
on a Mac, there is also an upgrade for Java 7 for the Mac available from 
http://java.oracle.com.  Java 6 for Mac OS-X has been controlled and 
distributed by Applie and I don't know if they have an updated version.

Hopefully, this will reduce the risk for anyone running Java on their 
machines.

Thanks,

John
