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.histogram_fixed_width` is vulnerable to a crash when the values array contain `Not a Number` (`NaN`) elements. The implementation assumes that all floating point operations are defined and then converts a floating point result to an integer index. If `values` contains `NaN` then the result of the division is still `NaN` and the cast to `int32` would result in a crash. This only occurs on the CPU implementation. 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.histogram_fixed_width" es vulnerable a un fallo cuando el array de valores contiene elementos "Not a Number" ("NaN"). La implementación asume que todas las operaciones de punto flotante están definidas y entonces convierte un resultado de punto flotante a un índice entero. Si "values" contiene "NaN" entonces el resultado de la división sigue siendo "NaN" y la conversión a "int32" resultaría en un bloqueo. Esto sólo ocurre en la implementación de la CPU. Las versiones 2.9.0, 2.8.1, 2.7.2 y 2.6.4 contienen un parche para este problema
