Patch Analysis for April 2017

Welcome to this April Patch Monday bulletin. This month delivers patches from Adobe, Google, Chrome and Oracle. Adobe remediated a large quantity of CVE’s for their products this month but so far there were no reported attacks in the wild. Take a look at Flash and then Acrobat/Reader first thing this month since they had the bulk of vulnerabilities affecting them and are targets for attacks. Review the remaining Adobe products to see if they are present in your environment and apply the patches as necessary. Two non-Microsoft browsers were patched this month but pay special attention to Mozilla. There were numerous vulnerabilities that could potentially result in arbitrary code execution and an array of other possible attacks. Google Chrome suffered from numerous vulnerabilities as well but they did not appear to be as severe as Firefox. Oracle released 8 new security fixes for Java this month. There were no known attacks on Java at the moment and the vulnerability details are limited but plan to follow your quarterly Java update plan (or create one if you do not have one).

LOGbinder: Feed Your SIEM a High Nutrition Diet

To achieve compliance and to stop APTs, your security analysts need to see what's happening in your applications and on your endpoints Unleash the power of native Windows Event Collection with Supercharger and track every endpoint with no agents, no polling and no noise. Put application audit logs where they belong – in your SIEM. Then correlate application security intelligence with the rest of your security activity. But getting application audit logs into your SIEM is surprisingly difficult. LOGbinder bridges the gap for a growing number of applications

So, without further ado, here's the chart of non-MS patches that affect Windows platforms in the past month.
