      "value": "Motoko's incremental garbage collector is impacted by an uninitialized memory access bug, caused by incorrect use of write barriers in a few locations. This vulnerability could potentially allow unauthorized read or write access to a Canister's memory. However, exploiting this bug requires the Canister to enable the incremental garbage collector or enhanced orthogonal persistence, which are non-default features in Motoko."

      "value": "El recolector de basura incremental de Motoko se ve afectado por un error de acceso a memoria no inicializada, causado por el uso incorrecto de barreras de escritura en algunas ubicaciones. Esta vulnerabilidad podr\u00eda permitir el acceso de lectura o escritura no autorizado a la memoria de un contenedor. Sin embargo, para explotar este error, es necesario que el contenedor habilite el recolector de basura incremental o la persistencia ortogonal mejorada, que son funciones no predeterminadas en Motoko."
