When processing .CCD files, data is read from file into a fixed-size stack buffer. Since no bounds checking is done, a buffer overflow can occur. Attackers can execute arbitrary code by convincing their victim to open an CCD file. NOTE: A file with the same base name, but the extension of "img" must also exist.
