Apple's iOS vulnerable to attack via Zero Day Exploit through prepared emails

Two security vulnerabilities in iOS have been actively exploited for several years. One patch has not yet been applied. Attackers can exploit the vulnerabilities via prepared emails that they send to their victims. Currently, iOS users should no longer use Apple's integrated mail app. Under iOS 12, the attacker email must be opened by the user. However, this e-mail does not contain any content. Under iOS 13, the attack can be carried out in the background without any user interaction. Only the mail app in the mobile operating system is affected. macOS is not affected.
