    description According to its banner, the remote host is running OpenSSL version 1.1.0a. It is, therefore, affected by a remote code execution vulnerability in the read_state_machine() function in statem.c due to improper handling of messages larger than 16k. An unauthenticated, remote attacker can exploit this, via a specially crafted message, to cause a use-after-free error, resulting in a denial of service condition or possibly the execution of arbitrary code.
