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.
Affected configurations
• canonical cloud-init (<= 19.4)
• opensuse leap 15.1
• debian debian linux 8.0
