An integer overflow in WhatsApp media parsing libraries allows a remote attacker to perform an out-of-bounds write on the heap via specially-crafted EXIF tags in WEBP images. This issue affects WhatsApp for Android before version 2.19.143 and WhatsApp for iOS before version 2.19.100.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
