December 2013 CU for SharePoint Server 2013 is planned to be released in a couple of days.
In case you are only interested in December CU for SharePoint Foundation 2013 or Office Web Apps Server 2013 you can already download it from here:
The Full Server Packages for December 2013 CU are available through the following links:
As announced March 2013 PU for SharePoint 2013 defined a new baseline for all future SharePoint fixes - so ensure to install March 2013 PU before installing SharePoint 2013 December CU.
The link to download SPF 2010 CU goes to a page where the product to be downloaded is described as
"Microsoft SharePoint Server 2013 All (Global) x64"
Of course this is probably only the usual inability of some MS people to think that SPS nnnn is the only SP product, but maybe in that case you can internally get them to correct the description on that page.
Another comment on that (download) page for passing on (which has however nothing to do with SharePoint).
Because my PC is set to Finnish keyboard and settings (to get EUR decimal comma etc) they are giving me that page in Finnish. In order to get it in English I need to sign in (where my sign-in settings must say I want English).
This to me is the wrong way round. They should give everyone the page in English. Then if someone wants it in some other language they should sign in (and have sign-in settings that give that other language).
Most computer professionals prefer using the English versions of all pages because they are accurate - unlike some of the translations - so that should always be the default.
yes, the name is not really helpful. but the fix name is: ubersts2013kb2849961fullfilex64glb.
As you can see it is the uber package for STS which is SharePoint foundation.
For you the language might be wrong. But ask an engineer in other countries.
Trust me: I'm involved in support cases in various different countries - and many engineers I work with don't understand english.
