Descriptions

Insufficient input validation in the Marvin Minsky 1967 implementation of the Universal Turing Machine allows program users to execute arbitrary code via crafted data. For example, a tape head may have an unexpected location after the processing of input composed of As and Bs (instead of 0s and 1s). NOTE: the discoverer states "this vulnerability has no real-world implications."

Una comprobación insuficiente de la entrada en la implementación de Marvin Minsky 1967 de Universal Turing Machine, permite a usuarios del programa ejecutar código arbitrario por medio de datos diseñados. Por ejemplo, un cabezal de cinta puede tener una ubicación inesperada después del procesamiento de una entrada compuesta por As y Bs (en lugar de 0s y 1s). NOTA: el descubridor afirma que "this vulnerability has no real-world implications"
