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, there is a potential for segfault / denial of service in TensorFlow by calling `tf.compat.v1.*` ops which don't yet have support for quantized types, which was added after migration to TensorFlow 2.x. In these scenarios, since the kernel is missing, a `nullptr` value is passed to `ParseDimensionValue` for the `py_value` argument. Then, this is dereferenced, resulting in segfault. 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, se presenta la posibilidad de que se produzca un fallo de seguridad o una denegación de servicio en TensorFlow al llamar a las operaciones "tf.compat.v1.*" que aún no presentan soporte para los tipos cuantificados, lo que fue añadido después de la migración a TensorFlow 2.x. En estos casos, al faltar el núcleo, es pasado un valor "nullptr" a "ParseDimensionValue" para el argumento "py_value". Entonces, este es desreferenciado, resultando en un segfault. Las versiones 2.9.0, 2.8.1, 2.7.2 y 2.6.4 contienen un parche para este problema
