Converting a string from Python to a tf.float16 value causes a segmentation fault in eager mode, because the format checks exist only in graph mode. An attacker can trigger a denial of service during inference or training by supplying a string where a tf.float16 value is expected, or by replacing a scalar tf.float16 value with a scalar string in saved models and checkpoints. The issue reproduces with tf.constant(\"hello\", tf.float16) when eager execution is enabled.","solution":"Patched in TensorFlow 1.15.1 and 2.0.1. TensorFlow 2.1.0 is not affected.
