      "value": "TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation of `tf.raw_ops.SparseReshape` can be made to trigger an integral division by 0 exception. The [implementation](https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/reshape_util.cc#L176-L181) calls the reshaping functor whenever there is at least an index in the input but does not check that shape of the input or the target shape have both a non-zero number of elements. The [reshape functor](https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/reshape_util.cc#L40-L78) blindly divides by the dimensions of the target shape. Hence, if this is not checked, code will result in a division by 0. We have patched the issue in GitHub commit 4923de56ec94fff7770df259ab7f2288a74feb41. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1 as this is the other affected version."

      "value": "TensorFlow es una plataforma de c\u00f3digo abierto de extremo a extremo para el aprendizaje autom\u00e1tico. En las versiones afectadas se puede hacer que la implementaci\u00f3n \"tf.raw_ops.SparseReshape\" lance una excepci\u00f3n de divisi\u00f3n integral por 0. La [implementaci\u00f3n](https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/reshape_util.cc#L176-L181) llama al functor de remodelaci\u00f3n siempre que haya al menos un \u00edndice en la entrada, pero no comprueba que la forma de la entrada o la forma objetivo tengan ambas un n\u00famero de elementos distinto de cero. El [functor de remodelaci\u00f3n](https://github.com/tensorflow/tensorflow/blob/8d72537c6abf5a44103b57b9c2e22c14f5f49698/tensorflow/core/kernels/reshape_util.cc#L40-L78) divide ciegamente por las dimensiones de la forma objetivo. Por lo tanto, si esto no es comprobado, el c\u00f3digo dar\u00e1 lugar a una divisi\u00f3n por 0. Hemos parcheado el problema en el commit 4923de56ec94fff7770df259ab7f2288a74feb41 de GitHub. La correcci\u00f3n se incluir\u00e1 en TensorFlow versi\u00f3n 2.6.0. Tambi\u00e9n se incluir\u00e1 este commit en TensorFlow versi\u00f3n 2.5.1 ya que es la otra versi\u00f3n afectada."
