The remote host is missing an update for the Huawei EulerOS 'cloud-init' package(s) announced via the EulerOS-SA-2020-2333 advisory. In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords. Cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function. Please install the updated package(s)
