Checking the first KB, it’s an advisory (from 2014) that has several patches associated with it, including 2871997, 2973351, 2982378, 2984972, 2984976, and 2984981. Any of these may be applicable to Win2008r2 depending upon which prior updates are installed. Are any of those KB’s rele ant to your system? They could also be superseded by a more current update.
It could be a false-negative in BigFix, or a false-positive in Windows Update. I’d make sure your systems are completely uo to date (according to BigFix) before checking for false-negatives.
