![]() ![]() ![]() Type confusion can allow an attacker to feed function pointers or data into the wrong piece of code. If the program doesn’t properly check that the input is actually a number and tries to perform arithmetic operations on it as if it were a number, it may produce unexpected results which could be abused by an attacker. Type confusion vulnerabilities are programming flaws that happen when a piece of code doesn’t verify the type of object that is passed to it before using it. So let’s say you have a program that expects a number as input, but instead it receives a string (i.e. The currently patched vulnerability was a type confusion issue that Apple says has been addressed with improved checks.

Apple has released information about the new security content of macOS Ventura 13.2.1 and of iOS 16.3.1 and iPadOS 16.3.1.
