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.SparseTensorToCSRSparseMatrix` 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 `dense_shape` is a vector and `indices` is a matrix (as part of requirements for sparse tensors) but there is no validation for this. 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.SparseTensorToCSRSparseMatrix" no comprueba completamente los argumentos de entrada. Esto resulta en un fallo de "CHECK" que puede ser usado para desencadenar un ataque de denegación de servicio. El código asume que "dense_shape" es un vector y que "indices" es una matriz (como parte de los requisitos para los tensores dispersos) pero no es comprobado esto. Las versiones 2.9.0, 2.8.1, 2.7.2 y 2.6.4 contienen un parche para este problema
