    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2020-14391:
    A flaw was found in the GNOME Control Center in Red Hat Enterprise Linux 8 versions prior to 8.2, where it
    improperly uses Red Hat Customer Portal credentials when a user registers a system through the GNOME
    Settings User Interface. This flaw allows a local attacker to discover the Red Hat Customer Portal
    password. The highest threat from this vulnerability is to confidentiality.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
