Debian LTS Advisory DLA-2601-1 [email protected]
https://www.debian.org/lts/security/ Utkarsh Gupta
March 20, 2021 https://wiki.debian.org/LTS
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:
https://security-tracker.debian.org/tracker/cloud-init
