Descriptions

TensorFlow is an open source platform for machine learning. In affected versions several TensorFlow operations are missing validation for the shapes of the tensor arguments involved in the call. Depending on the API, this can result in undefined behavior and segfault or `CHECK`-fail related crashes but in some scenarios writes and reads from heap populated arrays are also possible. We have discovered these issues internally via tooling while working on improving/testing GPU op determinism. As such, we don't have reproducers and there will be multiple fixes for these issues. These fixes will be included in TensorFlow 2.7.0. We will also cherrypick these commits 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, varias operaciones de TensorFlow no comprueban las formas de los argumentos del tensor involucrados en la llamada. Dependiendo de la API, esto puede resultar en un comportamiento indefinido y a caídas relacionadas con segfault o "CHECK"-fail, pero en algunos escenarios también son posibles las escrituras y lecturas de arrays poblados por la pila. Hemos detectado estos problemas internamente por medio de herramientas mientras trabajábamos en mejorar/probar el determinismo de las operaciones de la GPU. Por lo tanto, no tenemos reproductores y habrá múltiples correcciones para estos problemas. Estas correcciones serán incluidas en TensorFlow versión 2.7.0. También vamos a recoger estos commits 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
