Summary and TL;DR
Further to Apple’s patch of the MailDemon vulnerability (see our blog here), ZecOps Research Team has analyzed and compared the MailDemon patches of iOS 13.4.5 beta and iOS 13.5.
Our analysis concluded that the patches are different, and that iOS 13.4.5 beta patch was incomplete and could be still vulnerable under certain circumstances.
Since the 13.4.5 beta patch was insufficient, Apple issued a complete patch utilising a different approach which fixed this issue completely on both iOS 13.5 and iOS 12.4.7 as a special security update for older devices.
