Descriptions

Tensorflow is an Open Source Machine Learning Framework. The implementation of `AssignOp` can result in copying uninitialized data to a new tensor. This later results in undefined behavior. The implementation has a check that the left hand side of the assignment is initialized (to minimize number of allocations), but does not check that the right hand side is also initialized. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

Tensorflow es un Marco de Aprendizaje Automático de Código Abierto. La implementación de "AssignOp" puede resultar en la copia de datos no inicializados a un nuevo tensor. Esto luego resulta en un comportamiento indefinido. La implementación presenta una comprobación de que el lado izquierdo de la asignación está inicializado (para minimizar el número de asignaciones), pero no comprueba que el lado derecho también está inicializado. La corrección será incluida en TensorFlow versión 2.8.0. También seleccionaremos este commit en TensorFlow versión 2.7.1, TensorFlow versión 2.6.3, y TensorFlow versión 2.5.3, ya que estos también están afectados y aún están en el rango admitido
