AnyBurn 4.3 contains a local buffer overflow vulnerability that allows local attackers to crash the application by supplying an excessively long string in the image file name field. Attackers can paste a 10000-byte payload into the 'Image file name' parameter during the 'Copy disk to Image' operation to trigger a denial of service condition.
