An exploitable out of bounds write exists in the CAL parsing functionality of Canvas Draw version 5.0.0. A specially crafted CAL image processed via the application can lead to an out of bounds write overwriting arbitrary data. An attacker can deliver a PCX image to trigger this vulnerability and gain code execution.
The product writes data past the end, or before the beginning, of the intended buffer.
