More Java Woes

A number of readers alerted us of news reports stating that new "full sandbox escape" vulnerabilities had been reported to Oracle. At this point, there are no details available as to the nature of these vulnerabilities, and there is no evidence that any of these vulnerabilities are exploited. However, it is widely known that Oracle is working on a substantial backlog of these vulnerabilities. It is still recommended to use Java "with caution". Some best practices:

- Uninstall Java if you don't need it.
- if you do need Java, make sure it doesn't start automatically in your web browser.
- keep Java up to date
- reduce the number of Java variants you have installed to the minimum you need.

I wonder if you could use a QR code to launch this as well? I see people scanning QR codes everywhere, don"t know what you are going to get until it is too late.

Since a QR Code isn't much more than a link, it should work. FYI there is a QR-tool out from Symantec which checks QR-codes.

When I need to use Java, I use a copy of portable Firefox with Jportable (Portable Java) in the plugin folder. This works great and seems to be more reliable than the full version installed in my primary browser. I can have separate copies with different versions of Jportable in each to have specific Java versions available.
