I also haven't heard if any App-V packages are affected - another hallmark of the bad KB 2984872 patch last month.
TERMSRV DLL HAS AN UNKNOWN CHECKSUM RDP PATCHER TERMSRV.DLL MANUAL
There's no indication at this point if the manual solution works with KB 3003743. Microsoft has a far more complex solution in the KB 2984972 article. The easy solution last month was to uninstall the patch, and RDP started working again. This sounds reminiscent of the problems caused last month by KB 2984972, which also clobbered concurrent RDP sessions on some machines. Jason Hart has also tweeted that KB 3003743 kills NComputing's virtualization software. Today's updates includes KB3003743 and with it comes termsrv.dll version. Poster turducken on the My Digital Life forums pins it down: I'm seeing sporadic reports of KB 3003743 - part of MS14-074 - breaking concurrent RDP sessions. If so, that's a very positive development. Presumably Microsoft caught bugs in the patches and pulled them at the last minute. Both MS14-068 and MS14-075 are listed in the official Security Bulletin summary as "Release date to be determined." I've never seen that designation before.
Microsoft voluntarily pulled two Security Bulletins (with an unknown number of associated patches) before they were released. This month's Black Tuesday patches started out with an odd - though hopeful - sign. But the patches themselves are only part of the story. With 14 security updates that include fixes for 33 separately identified security holes, 14 new nonsecurity patches, two changes to the installers for older security patches, and three changes for older nonsecurity updates, November's Black Tuesday is going down as one of the weightiest ever.
