Descriptions

Tensorflow is an Open Source Machine Learning Framework. The `simplifyBroadcast` function in the MLIR-TFRT infrastructure in TensorFlow is vulnerable to a segfault (hence, denial of service), if called with scalar shapes. If all shapes are scalar, then `maxRank` is 0, so we build an empty `SmallVector`. The fix will be included in TensorFlow 2.8.0. This is the only affected version.

Tensorflow es un Marco de Aprendizaje Automático de Código Abierto. La función "simplifyBroadcast" en la infraestructura MLIR-TFRT en TensorFlow es vulnerable a un segfault (por lo tanto, denegación de servicio), si es llamado con formas escalares. Si todas las formas son escalares, entonces "maxRank" es 0, por lo que construimos un "SmallVector" vacío. La corrección será incluida en TensorFlow versión 2.8.0. Esta es la única versión afectada
