Session operations in eager mode lead to null pointer dereferences

Impact In eager mode default in TF 2.0 and later, session operations are invalid. However, users could still call the raw ops associated with them and trigger a null pointer dereference: python import tensorflow as tf tf.rawops.GetSessionTensorhandle='\x12\x1a\x07',dtype=4 python import tensorflo...
