Apple no longer supports the Windows variant of QuickTime so the DHS says you should uninstall the software to avoid a "loss of confidentiality, integrity, or availability of data, as well as damage to system resources or business assets."
Security firm Trend Micro made a similar announcement earlier this week, although they noted that there have not been any successful attacks using the exploits that they know of.
There's actually a pretty good chance you don't have QuickTime installed, anyways, especially since it does not run on Windows 8 or Windows 10, but if you are running an older operating system it may be time to uninstall the app.
