Descriptions

Tensorflow is an Open Source Machine Learning Framework. The implementation of `AddManySparseToTensorsMap` is vulnerable to an integer overflow which results in a `CHECK`-fail when building new `TensorShape` objects (so, an assert failure based denial of service). We are missing some validation on the shapes of the input tensors as well as directly constructing a large `TensorShape` with user-provided dimensions. 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 "AddManySparseToTensorsMap" es vulnerable a un desbordamiento de enteros que resulta en un fallo de "CHECK" cuando son construidos nuevos objetos "TensorShape" (por tanto, una denegación de servicio basada en un fallo de assert). Nos falta algo de comprobación en las formas de los tensores de entrada, así como construir directamente un "TensorShape" grande con las dimensiones proporcionadas por el usuario. 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
