SUSE SLES12 Security Update : cloud-init (SUSE-SU-2023:2164-1)

medium Nessus Plugin ID 175592

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2164-1 advisory.

 - When instructing cloud-init to set a random password for a new user account, versions before 21.2 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)

 - Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege. (CVE-2023-1786)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected cloud-init and / or cloud-init-config-suse packages.
