Certain input files may trigger an integer overflow in ttembed input file processing. This overflow could potentially lead to corruption of the input file due to a lack of checking return codes of fgetc/fputc function calls.
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.
