"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2022:0033 advisory.

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

    CVE-2022-27649:
    A flaw was found in Podman, where containers were started incorrectly with non-empty default permissions.
    A vulnerability was found in Moby (Docker Engine), where containers were started incorrectly with non-
    empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with
    inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.

    CVE-2022-27651:
    A flaw was found in buildah where containers were incorrectly started with non-empty default permissions.
    A bug was found in Moby (Docker Engine) where containers were incorrectly started with non-empty
    inheritable Linux process capabilities, enabling an attacker with access to programs with inheritable file
    capabilities to elevate those capabilities to the permitted set when execve(2) runs. This has the
    potential to impact confidentiality and integrity.

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

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