CVE-2020-8631 (opens in a new tab)Amendment
The SLES security team deemed this advisory irrelevant for SLES:15.1.
NVD Description
Note: Versions mentioned in the description apply only to the upstream cloud-init-doc package and not the cloud-init-doc package as distributed by SLES.
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.
