====================
Updated: 21st March 2019
====================
Two of the vulnerabilities patched by Microsoft (CVE-2019-0797, CVE-2019-0808) were zero day (defined) vulnerabilities being actively exploited in the wild. Four other vulnerabilities were publicly known (CVE-2019-0683, CVE-2019-0754, CVE-2019-0757 and CVE-2019-0809).
Separately the Google Chrome vulnerability mentioned below namely CVE-2019-5786 was also being exploited by attackers.
After publishing my original post; Adobe and Microsoft jointly reported that while a newer version (32.0.0.156) of Flash Player was made available it only resolves non-security bugs.
I have updated the suggested installation order (below) to reflect this new information. Thank you.
====================
Original Post:
====================
As scheduled; earlier today Microsoft and Adobe made available their security updates. Microsoft addressed 65 vulnerabilities (more formally known as CVEs (defined)) with Adobe resolving 2 vulnerabilities.
For Adobe; if you have not already done so; if you manage an installation of Adobe ColdFusion or know someone who does, please apply the necessary updates made available earlier this month. That update addressed a single priority 1 zero day (defined) vulnerability being exploited in the wild. Today’s Adobe updates are as follows:
Adobe Digital Editions: 1x priority 3 CVE resolved
Adobe Photoshop CC: 1x priority3 CVE resolved
If you use the affected Adobe products; please install their remaining priority 3 updates when you can.

Google Chrome:
=======================
Google released Google Chrome version 72.0.3626.121 to address a single zero day (defined) vulnerability under active exploit. The vulnerability was a high severity use-after-free (defined) flaw in Chrome’s FileReader API (defined) which could have led to information disclosure of files stored on the same system as Chrome is installed.
Google Chrome updates automatically and will apply the update the next time Chrome is closed and then re-opened. Chrome can also be updated immediately by clicking the Options button (it looks like 3 stacked small horizontal lines, sometimes called a “hamburger” button) in the upper right corner of the window and choosing “About Google Chrome” from the menu. Follow the prompt to Re-launch Chrome for the updates to take effect.
