Microsoft delayed February Patch Tuesday on February 14, 2017 and a week later posted a critical patch for a remote code execution via Adobe Flash Player in certain Windows OSes.  IT Security strongly recommends applying the patch on Windows 8.1 and up for workstations as well as Windows 2012 Server and up for servers.

A HIGH vulnerability, CVE-2017-6074, that has existed in the Linux kernel since 2005 is about to have a proof-of-concept exploit released by a Google researcher.  It is related to an esoteric network traffic control protocol on the application layer (DCCP) that some distros of LINUX default configured.  Some distros have already responded in the last 24 hours with a patch package and some are recommending blacklisting the dccp module.  Please review your Linux distro’s response to the vulnerability.
