libcdio print_iso9660_recurse() buffer overflow

libcdio-printiso9660recurse-bo (39405) The risk level is classified as HighHigh Risk


GNU Compact Disc Input and Control Library (libcdio) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the print_iso9660_recurse() function in the cd-info and iso-info applications. By persuading a victim to use an iso-info application on a specially-crafted disk or image containing an overly long joilet file name, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
