NTSC-CRT 2.2.1 has an integer overflow and out-of-bounds write in loadBMP in bmp_rw.c because a file's width, height, and BPP are not validated. NOTE: the vendor's perspective is "this main application was not intended to be a well tested program, it's just something to demonstrate it works and for the user to see how to integrate it into their own programs."
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.
