Zero-day vulnerabilities patched
Now matter how prepared you are, Patch Tuesday never fails to throw in a surprise. What’s so special about this one is that four zero-day vulnerabilities published by a security researcher named SandboxEscaper—CVE-2019-0973, CVE-2019-1053, CVE-2019-1064, CVE-2019-1069—are patched in this month’s roll-up update. Though publicly disclosed, none of these vulnerabilities have been actively exploited in the wild. And all four belong to the same category of vulnerability: elevation of privilege.
Critical vulnerabilities patched
Patches were also released for three critical remote code execution (RCE) vulnerabilities discovered in Hyper-V, native virtualization software that lets users run multiple operating systems simultaneously as virtual machines. These flaws originated from host machines failing to properly validate input from an authenticated user on a guest operating system.
Other important RCE vulnerabilities
Microsoft also patched four RCE flaws in Microsoft HoloLens devices, nine in Chakra Scripting Engine (included with Edge), two in Microsoft’s NTLM authentication protocol, four in Microsoft Scripting Engine, one in Microsoft Speech API, and one impacting both Edge and Internet Explorer.
Third-party patches: Adobe updates
Adobe, another tech giant, has also released security updates to address 11 security vulnerabilities in its products. Of those, three vulnerabilities in Adobe ColdFusion, one in the infamous Flash Player, and one in Adobe Campaign Classic are rated as critical and could lead to arbitrary code execution attacks.
One way to patch all your Patch Tuesday updates at once: Automated patch deployment
Too many patches should never be the reason for poor patching. A single vulnerability has the potential to turn your business upside down. With Desktop Central at your disposal, you can automate the mountain of patches that are being released every Patch Tuesday to any number of machines in your network. Plus, you can utilize the Test and Approve feature to test-drive patches before rolling them out to production machines.
