Package        : cloud-init
Version        : 0.7.9-2+deb9u1
CVE ID         : CVE-2021-3429
Debian Bug     : 985540

cloud-init has the ability to generate and set a randomized password
for system users.  This functionality is enabled at runtime by
passing cloud-config data such as:

   chpasswd:
       list: |
           user1:RANDOM

When used this way, cloud-init logs the raw, unhashed password to a
world-readable local file.

For Debian 9 stretch, this problem has been fixed in version
0.7.9-2+deb9u1.

We recommend that you upgrade your cloud-init packages.

For the detailed security status of cloud-init please refer to
its security tracker page at:
