An exploitable code execution vulnerability exists in the TIFF fillinraster function of the igcore19d.dll library of Accusoft ImageGear 19.4, 19.5 and 19.6. A specially crafted TIFF file can cause an out-of-bounds write, resulting in remote code execution. An attacker can provide a malicious file to trigger this vulnerability.
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.
