This week’s security update takes the Office 2013-based Lync/SfB client from 15.0.4771.1001 to 15.0.4779.1001.
Kb3114351 "MS15-128: Description of the security update for Lync 2013 (Skype for Business): December 8, 2015
This security update resolves vulnerabilities in Microsoft Lync 2013 and Skype for Business. The vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a webpage that contains specially crafted embedded fonts.
To learn more about the vulnerabilities, see Microsoft Security Bulletin MS15-128.
For a complete list of affected software, see Microsoft Knowledge Base article 3104503".
This security update fixes the following non-security-related issues:
- When you are in a public switched telephone network (PSTN) call, and you open a Conversation Window Extension (CWE), the call option controls are covered by the CWE without any way to access the controls without closing the CWE.
- Lync client doesn’t show all the fonts if the computer has more than 1,000 fonts.
- Kb3114328 "You need to install the April 14, 2015 update" error message is displayed when you start Lync 2013

What’s New / Changed
This security update contains the following improvements:
- Adds Cloud-based Discovery
- Uses SSO to autodetect SIP address and start sign in
I’ve highlighted the one new/updated pre-req here – the new version of “lynchelploc”.
A few people have found their recent updates haven’t delivered as expected. Don’t forget *all* of the 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).
|Update for Office 2013 (KB3054853) (NOTE 1 BELOW)||1.0||9 June 2015|
|LyncHelpLoc (Kb3039776)||1.0||1 December 2015|
|Microsoft Office 2013 Language Pack Service Pack 1 (KB2817427)||1.0||13 February 2014|
NOTE1: “You do not have to apply update KB3054853 if you applied the April 14, 2015, update (KB2889923) or the May 12, 2015, security update (KB3039779) for Lync 2013 (Skype for Business)”
This is the client fix itself:
I have all the pre-req’s already installed, so a reboot was not required. I was however running Outlook 2013 at the time and I was prompted to exit it, to which I duly complied.
