A couple of the most notorious SVO’s  [Security Vulnerability Offenders] are back again with ‘critical’ updates.

If you have Java or Flash on your computer [Who doesn't?], please make sure you update to the latest versions.

At this writing, for Java, that would be version 6 update 24.

Flash is more complicated as there are multiple versions depending on your browser.  As of this writing, Flash for 32 bit Internet Explorer would be version 10.2.152.26.  For 64 bit IE, it would be version 10.2.161.23.

(by the way, these new versions also provide enhanced performance.)

Generally speaking, if you visit the above addresses with the browser of your choice, you will be offered the correct version.

[After all, what could possibly go wrong?]
