Descriptions

In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, by controlling the `fill` argument of tf.strings.as_string, a malicious attacker is able to trigger a format string vulnerability due to the way the internal format use in a `printf` call is constructed. This may result in segmentation fault. The issue is patched in commit 33be22c65d86256e6826666662e40dbdfe70ee83, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.

En Tensorflow versiones anteriores a 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, al controlar el argumento "fill" de tf.strings.as_string, un atacante malicioso puede desencadenar una vulnerabilidad de cadena de formato debido a la manera en que se construye el uso del formato interno en una llamada de "printf". Esto puede resultar en un fallo de segmentación. El problema es parcheado en el commit 33be22c65d86256e6826666662e40dbdfe70ee83 y es publicado en TensorFlow versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 o 2.3.1
