I noticed today the Secunia PSI had a flag saying Flash Player had updated. I checked Adobe Flash Player Settings Manager and sure enough, both the ActiveX and the Firefox plugin version had automatically and silently updated to 184.108.40.2066.
The new version isn't listed on the Adobe site at this time of posting.
UPDATE (January 24): users who have enabled auto-update for the Flash Player desktop runtime will be receiving version 220.127.116.116 beginning on January 24. This version includes a fix for CVE-2015-0311. Adobe expects to have an update available for manual download during the week of January 26, and we are working with our distribution partners to make the update available in Google Chrome and Internet Explorer 10 and 11. For more information on updating Flash Player, please refer to this post. We will continue to provide updates on this issue via the Adobe PSIRT blog.
