The message containing the malware is doing rounds around the world.
However, the iPhone crashes when the user tries to open Messages again, throwing up a white screen.
Apple will most likely fix this issue for all affected users via an OTA update soon.
This is not the first time a bug has been discovered in iMessage app.
If the iPhone was locked when the offending message was received, the iPhone supposedly rebooted without notice.
However, Apple later introduced a fix for the text crash.
