Descriptions

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of `tf.raw_ops.UnsortedSegmentJoin` does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack. The code assumes `num_segments` is a positive scalar but there is no validation. Since this value is used to allocate the output tensor, a negative value would result in a `CHECK`-failure (assertion failure), as per TFSA-2021-198. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.

TensorFlow es una plataforma de código abierto para el aprendizaje automático. En versiones anteriores a 2.9.0, 2.8.1, 2.7.2 y 2.6.4, la implementación de "tf.raw_ops.UnsortedSegmentJoin" no comprobaba completamente los argumentos de entrada. Esto resulta en un fallo de "CHECK" que puede usarse para desencadenar un ataque de denegación de servicio. El código asume que "num_segments" es un escalar positivo, pero no lo comprueba. Dado que este valor es usado para asignar el tensor de salida, un valor negativo resulta en un fallo de "CHECK" (fallo de aserción), según TFSA-2021-198. Las versiones 2.9.0, 2.8.1, 2.7.2 y 2.6.4 contienen un parche para este problema
