In ffjpeg (commit hash: caade60), the function bmp_load() in bmp.c contains an integer overflow vulnerability, which eventually results in the heap overflow in jfif_encode() in jfif.c. This is due to the incomplete patch for issue 38
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.
