Descriptions

In affected versions of TensorFlow the tf.raw_ops.DataFormatVecPermute API does not validate the src_format and dst_format attributes. The code assumes that these two arguments define a permutation of NHWC. This can result in uninitialized memory accesses, read outside of bounds and even crashes. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.

En las versiones afectadas de TensorFlow, la API tf.raw_ops.DataFormatVecPermute no comprueba los atributos src_format y dst_format. El código asume que estos dos argumentos definen una permutación de NHWC. Esto puede resultar en accesos de memoria no inicializados, lectura fuera de límites e incluso fallos. Esto es corregido en las versiones 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 y 2.4.0.
