Fixed leak of cross user data in multiple settings.
- Any app is allowed to receive GET_CONTENT intent. Using this, an user puts back in the intent an uri with data of another user.
- Telephony service has INTERACT_ACROSS_USER permission. Using this, it reads and shows the deta to the evil user.
Fix: When telephony service gets the intent result, it checks if the uri is from the current user or not.
Bug: b/256591023 , b/256819787
Test: The malicious behaviour was not being reproduced. Unable to import contact from other users data.
Test2: Able to import contact from the primary user or uri with no user id
(These settings are not available for secondary users)
