Descriptions

TensorFlow is an open source platform for machine learning. In affected versions the implementation of `SparseBinCount` is vulnerable to a heap OOB access. This is because of missing validation between the elements of the `values` argument and the shape of the sparse output. 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.

TensorFlow es una plataforma de código abierto para el aprendizaje automático. En las versiones afectadas, la implementación de "SparseBinCount" es vulnerable a un acceso OOB a la pila. Esto es debido a la falta de comprobación entre los elementos del argumento "values" y la forma de la salida dispersa. La corrección será incluida en TensorFlow versión 2.7.0. También vamos a incluir este commit en TensorFlow versión 2.6.1, TensorFlow versión 2.5.2, y TensorFlow versión 2.4.4, ya que estos también están afectados y todavía en el rango admitido
