Test ID:1.3.6.1.4.1.25623.1.1.10.2021.0494
Category:Mageia Linux Local Security Checks
Title:Mageia: Security Advisory (MGASA-2021-0494)
Summary:The remote host is missing an update for the 'cloud-init' package(s) announced via the MGASA-2021-0494 advisory.
Description:Summary:
The remote host is missing an update for the 'cloud-init' package(s) announced via the MGASA-2021-0494 advisory.

Vulnerability Insight:
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 instructing cloud-init to set a random password for a new user
account, versions before 21.1.19 would write that password to the
world-readable log file /var/log/cloud-init-output.log. This could allow a
local user to log in as another user (CVE-2021-3429).

Affected Software/OS:
'cloud-init' package(s) on Mageia 8.

Solution:
Please install the updated package(s).

CVSS Score:
4.6
