Alpine: multiple chrony packages: security update to 3.5-r2 (deprecated)

medium Tenable Self-Hosted Container Security Plugin ID 400381

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony
folder. The file is created during chronyd startup while still running as the root user, and when it's
opened for writing, chronyd does not check for an existing symbolic link with the same file name. This
flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing
to any destination file in the system, resulting in data loss and a denial of service due to the path
traversal. (CVE-2020-14367)
