April Patch Tuesday: Stop Active Exploits
Microsoft's security release for April covers 74 vulnerabilities in a wide range of products, including two actively exploited zero-days.
Microsoft have released 74 patches today covering IE, Edge, Exchange, Windows and Office. There are 13 rated Critical and 61 are Important. In this release there are no Moderate or Low in severity but this is up over last month’s release of 64 updates, this release will keep you busy.
Prioritize Active Exploits
Two of the updates CVE-2019-0803 and CVE-2019-0859 are “Being Exploited” meaning you should prioritise them now. Robert Brown, Director of Services for Verismic said, “You should treat these updates with the highest importance because a similar vulnerability this year in Win32k elevation caused some significant global intrusions via malware infections.”
Adobe Updates
Adobe have released 8 updates today, for Reader, Flash, Shockwave, InDesign and Dreamweaver and a few others. The update for Flash is Critical meaning IT Admins should install these updates within the next 30 days.
Some Features Updates are Now Retired
Act now to keep your environment future proofed as updates will automatically uninstall.
Today the Windows 10 feature update version 1709 (and previous) is retired on Home, Pro and Pro for Workstations editions. If you try to deploy any security updates / patches to Windows 10 which are no longer supported, those updates will uninstall the next time the PC restarts. Ask your account manager how Syxsense can help you deploy your Windows 10 Feature Updates.
We have made a few recommendations below which you should prioritize, use Syxsense to organize and deploy Windows, third-party, Mac OS, and Linux updates to keep your environment safe.
