There is an integer overflow vulnerability in dcraw. When the victim runs dcraw with a maliciously crafted X3F input image, arbitrary code may be executed in the victim's system.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
The 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.
