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.
Notes
| Author | Note |
|---|---|
| ccdm94 | This CVE has been patched in Xenial ESM. The patch, however, has been added only to the updates pocket, and since cloud-init is only used during first boot (pulling from updates), there should not be a need to add this to the security pocket. |
