CVE-2012-3744
Telephony in Apple iOS before 6 uses an SMS message's return address as the displayed sender address, which allows remote attackers to spoof text communication via a message in which the return address does not match the originating address.
Does this matter?
Lower severity and a low EPSS score (1.91%). Track it; it rarely justifies an emergency change on its own.
