KB3038314 – MS15-032: Cumulative security update for Internet Explorer
KB3049508 – Microsoft security advisory: Update for vulnerabilities in Adobe Flash Player in Internet Explorer:
KB3060429 – ??? [no support page render on the Microsoft site]
KB3060435 – ??? [no support page render on the Microsoft site]
