Descriptions

realloc_symlink in rock.c in GNU libcdio before 1.0.0 allows remote attackers to cause a denial of service (NULL Pointer Dereference) via a crafted iso file.

realloc_symlink en rock.c en GNU libcdio, en versiones anteriores a la 1.0.0, permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL) mediante un archivo iso manipulado.

A NULL pointer dereference flaw was found in the way libcdio handled processing of ISO files. An attacker could potentially use this flaw to crash applications using libcdio by tricking them into processing crafted ISO files.
