Patch Tuesday, April 2018

April's Patch Tuesday didn't let up much compared to March. Overall April brings with it patches for 70 vulnerabilities including 27 rated as "Critical", 42 rated as "Important" and 1 rated as "Moderate". Along with most of our "usual suspects", the MS Chakra Scripting Engine is back this month with seven RCE vulnerabilities patched. The MS Chakra Scripting Engine is implemented in Internet Explorer 9 as an interpreter for Microsoft's JScript language and made its first appearance last month with eight CVEs patched.

The big news this month is the out of band patch released for Microsoft Malware Protection Engine. The vulnerability (CVE-2018-0986) is a remote code execution bug in a DLL used by the Malware Protection Engine. It's always unfortunate when the software we use to protect us actually put us at more risk. Luckily the vulnerability was discovered by security researchers at Google instead of by criminals, so we have a chance to patch this vulnerability before it gets exploited.

The vulnerabilities rated as "Important" also includes many patches to be aware of. This list includes patches for server software that is often positioned with public access leaving them more at risk. Affected packages include HTTP.sys, Hyper-V, and SharePoint. Client software doesn't escape either as there are dozens of patches that fix vulnerabilities in IE, Edge, the MS Graphics Engine, and the Office suite, including RCE issues in MS Excel.

Let's hope that May's release is smaller, but until then let's get patching.
