RHEL 8 : cloud-init (RHSA-2020:4650)

medium Nessus Plugin ID 142375

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:4650 advisory.

The cloud-init packages provide a set of init scripts for cloud instances. Cloud instances need special scripts to run during initialization to retrieve and install SSH keys, and to let the user run various scripts.

Security Fix(es):

* cloud-init: Use of random.choice when generating random password (CVE-2020-8631)

* cloud-init: Too short random password length in cc_set_password in config/cc_set_passwords.py (CVE-2020-8632)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Additional Changes:

For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.3 Release Notes linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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 package.
