If you are unaware of the "Master-Key security vulnerability", please read the report:
http://bluebox.com/corporate-blog/bluebox-uncovers-android-master-key/

This patch is based on the official patch codebase from Google, adapted as Xposed module.

To test whether you are actually protected by this patch, try installing this proof-of-concept demo apk:

If it says "not installed", congratulations, you are now immune to Master-Key vulnerability!

NOTE: BlueboxScanner may still report your device as "Unpatched/vulnerable". Just relax, its a false report. Do a real test with the above PoC demo.
