Microsoft Security Updates

Number: AV17-081
Date: 13 June 2017

Purpose

The purpose of this advisory is to bring attention to recently released Microsoft Security Updates.

Assessment

The summary covers multiple support package deployments addressing multiple vulnerabilities in various Microsoft products (including Internet Explorer, Microsoft Edge, Microsoft Windows, Microsoft Office and Microsoft Office Services and Web Apps, Silverlight, Skype for Business and Lync, Adobe Flash Player).

As part of this set of security updates, Microsoft has also released updates addressing critical vulnerabilities in some older unsupported versions of Windows.  This is due to an increased threat of exploitation based on recent attacks and disclosures.

Suggested Action

CCIRC recommends that system administrators test and deploy the vendor-released updates to affected applications accordingly.
