Five bugs in Apple s iMessage service for the iPhone have been uncovered that require no user interaction to exploit. Apple has fully patched four of the flaws as part of the 12.4 iOS update. An exploit could leak the SMS database, binary files like images and more. The potential for information exfiltration is significant, iOS users should take care to upgrade to the latest version of iOS 12.0, 12.1 or 12.2, etc. A security researcher has made a proof-of-concept public for the flaw.
