      "value": "Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.\n\nretrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value.\n\nA crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization."

      "value": "Las versiones de Storable anteriores a la 3.41 para Perl tienen un desbordamiento de entero con signo al deserializar un registro SX_HOOK manipulado.\n\nretrieve_hook_common lee un recuento de elementos con signo de 32 bits de un registro SX_HOOK y llama a av_extend con ese recuento más uno. Un recuento de I32_MAX envuelve la adición a un valor negativo.\n\nUn blob manipulado pasado a thaw o retrieve desencadena el desbordamiento; av_extend recibe el recuento negativo y termina con un pánico, finalizando la deserialización."
