Microsoft kicked off 2019 with a light Patch Tuesday listing 47 vulnerabilities with seven rated as critical.

The seven critical issues all could lead to remote code execution and primarily impact Microsoft Edge, various versions of Windows 10 and Server and Chakra Core. The other overriding vulnerability, CVE-2018-8653, was patched by Microsoft in December, but industry analysts all reiterated the need for users to download the update.

“The Jscript vulnerability allows an attacker to leverage the scripting engine within IE by simply viewing a malicious website. Once successful, the attacker can gain control of the system with the user’s rights. So if you did the December Patch Tuesday updates, but did not catch the out of band, you will want to ensure all of your Windows systems get either the January Cumulative Update or the IE update as quickly as possible,” said Chris Goettl, Ivanti’s director of product management, security.
