Patch Tuesday, May 2018

May's Patch Tuesday is here and it looks like these monthly releases have plateaued at around 70 CVEs patched per month. May comes in with 68 CVEs total including 21 rated "Critical", 44 rated "Important", and three rated "Low".

Among the Critical vulnerabilities, issues with the Microsoft Scripting engine continues to plague Microsoft products. Any product from IE to Office that can execute VBscript or Javascript could be vulnerable to remote code execution. Also included in the Critical list are two remote code execution vulnerabilities for the Hyper-V cloud platform.

May's release also contains the out of band patch for CVE-2018-8115 affecting the Windows Host Compute Service Shim library. This service allows for the launch of Windows Server containers from services like Docker. A malicious container could allow an attacker to execute arbitrary code on any system installing (or "pulling") the container. Microsoft issued an out of band patch for this vulnerability last week, but rolled it up into Patch Tuesday for those that didn't manually install the patch.

Among the Important and Low rated vulnerabilities, there are dozens of vulnerabilities patched for server platforms like SharePoint and Exchange Server as well as client software like the Office Suite, Outlook, IE and Edge.
