In affected versions the shape inference code for the `Cudnn*` operations in TensorFlow can be tricked into accessing invalid memory, via a heap buffer overflow. This occurs because the ranks of the `input`, `input_h` and `input_c` parameters are not validated, but code assumes they have certain values. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range."},{"lang":"es","value":"TensorFlow es una plataforma de código abierto para el aprendizaje automático. En las versiones afectadas, el código de inferencia de formas para las operaciones \"Cudnn*\" en TensorFlow puede ser engañado para acceder a memoria no válida, por medio de un desbordamiento del buffer de la pila.
