Lync 2013 / SfB 2015 Client Security Update – September 2017

It’s been a month since our last update to the Office 2013-based Lync/SfB client took us to 15.0.4953.1000. Today, a security update takes us to 15.0.4963.1000.

Kb 4011107: This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a specially crafted Office file. To learn more about these vulnerabilities, see Microsoft Common Vulnerabilities and Exposures CVE-2017-8676, Microsoft Common Vulnerabilities and Exposures CVE-2017-8695, and Microsoft Common Vulnerabilities and Exposures CVE-2017-8696.

What’s Fixed

Two other items are addressed in this update:

  • Kb 4039811 Doesn’t display a dialog box to join a meeting through a web browser if Skype for Business 2015 sign-in fails
  • Translate some terms in multiple languages to make sure that the meaning is accurate.

Pre-Req’s

It’s been a big year for pre-req updates, but if you’re current then you’re OK today.

If however your patching isn’t to current you’ll need to check you have *all* of these pre-req’s. The Office 2013 SP1 requirement still applies if you’re using Outlook 2010. (Lync 2013 in all of its flavours – e.g. Lync Basic – is still a component of Office 2013).
