Flash
There is a new zero-day vulnerability targeting Adobe Flash.  It has been added to an "exploit kit" which makes it very simple for the exploit to be utilized.  And it is confirmed that it is indeed being spotted actively being exploited.  The update to fix it is expected to be released within a week.  In the meantime, some are recommending that you disable Flash in your browser.  Others are reporting that using Chrome is good enough as it appears to have immunity.
