An exploitable integer overflow vulnerability exists in the JPEG 2000 parser functionality of IrfanView 4.44. A specially crafted jpeg2000 image can cause an integer overflow leading to wrong memory allocation resulting in arbitrary code execution. Vulnerability can be triggered by viewing the image in via the application or by using thumbnailing feature of IrfanView.
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.
