The product group released the December 2020 Cumulative Update for the SharePoint 2013 product family.
For December 2020 CU we have full server packages (also known as Uber packages) for all products. No other CU is required to fully patch SharePoint.
As this is a common question: Yes, December 2020 CU includes all fixes from December 2020 PU.
ATTENTION:
Be aware that all Updates for SharePoint 2013 require SharePoint Server 2013 SP1 to be installed first.
Please also have a look at the article that discusses how to properly patch a SharePoint 2013 farm which has Search enabled (see below).
Previous releases of the SharePoint Server 2013 cumulative update included both the executable and the .CAB file in the same self-extracting executable download. Because of the file size, the SharePoint Server 2013 package has been divided into several separate downloads. One contains the executable file, while the others contain the CAB file. All are necessary and must be placed in the same folder to successfully install the update. All are available by clicking the same Hotfix Download Available link in the KB article for the release.
This CU includes all SharePoint 2013 fixes (including all SharePoint 2013 security fixes) released since SP1. The CU does not include SP1. You need to install SP1 before installing this CU.
The KB articles for December 2020 CU should be available at the following locations in a couple of hours:
- KB 4486761 – SharePoint Foundation 2013 December 2020 CU
- KB 4493137 – SharePoint Server 2013 December 2020 CU
- KB 4486763 – Project Server 2013 December 2020 CU
- KB 4486760 – Office Web Apps Server 2013 December 2020 CU
The Full Server Packages for December 2020 CU are available through the following links:
- Download SharePoint Foundation 2013 December 2020 CU
- Download SharePoint Server 2013 December 2020 CU
- Download Project Server 2013 December 2020 CU
- Download Office Web Apps Server 2013 December 2020 CU
After installing the fixes you need to run the SharePoint 2013 Products Configuration Wizard on each machine in the farm. If you prefer to run the command line version psconfig.exe ensure to have a look here for the correct Options.
Be aware that the SharePoint Server 2013 CU contains the SharePoint Foundation 2013 CU. And the Project Server 2013 CU also contains the SharePoint Server 2013 CU and SharePoint Foundation 2013 CU.
Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.

Hi Stefan, first of all, thank you for putting the time and effort into this blog, really appreciate it! 🙂 I have a question I hope you can help me with. We are still running SharePoint 2013 SP1 on WS 2008 R2. We have always applied the latest CU in a test environment first, and then installing them in the prod environment if everything is ok. However, we know the system requirements for SP13 CU are WS 2012 or 2012 R2, and therefore we are getting more hesitant with applying these security fixes. Would you recommend that we stop installing new CUs?

Hi Michelle,
the reason that Window Server 2008 R2 is not listed is because this operating system is unsupported since around one year already.
No fixes including security fixes are created anymore for this operating system.
Running a productive SharePoint environment on a completely unsupported OS will be very risky and you should look into upgrading your operating system soon.
The SharePoint fixes themselves do not have specific dependencies on the OS version.
Cheers,
Stefan

We noticed after applying the patches that URLs with dash in it were removed from the search index. Has anyone reported this issue?

Hi Josephine,
this has not been reported so far. I would recommend to open a case with Microsoft support to get this analyzed.

Hi Stefan,
Thanks for providing information related to CU, really helps.
I am planing to install this CU on our SharePoint farm (App1, App2, Wfe1, Wfe2). So just wanted to confirm that should I install CU first on all servers and then run config wizard sequentially
Or
Should I go with one after the other like
Install CU on APP1 and run config wizard
Install CU on App2 and run config wizard
Install CU on WFE1 and run config wizard
Install CU on WFE2 and run config wizard
Can you please confirm which process I need to follow? Also should I install CU on App first or WFE first?
Thanks & regards

Hi Nitin,
it is important that the fix has been installed on all servers in the farm before running PSConfig.
So the first approach is correct.
Cheers,
Stefan
