In Apache Mesos versions pre-1.4.2, 1.5.0, 1.5.1, 1.6.0 the comparison of the generated HMAC value against the provided signature in the JWT implementation used is vulnerable to a timing attack because instead of a constant-time string comparison routine a standard `==` operator has been used. A malicious actor can therefore abuse the timing difference of when the JWT validation function returns to reveal the correct HMAC value."},{"lang":"es","value":"Apache Mesos puede configurarse para que requiera autenticación para llamar a la API HTTP Executor utilizando JSON Web Token (JWT). En las versiones de Apache Mesos anteriores a la 1.4.2, 1.5.0, 1.5.1 y 1.6.0, la comparación del valor HMAC generado con la firma proporcionada en la implementación de JWT utilizada es vulnerable a un ataque de sincronización porque, en lugar de una rutina de comparación de cadenas de tiempo constante, se ha utilizado un operador estándar \"==\".
