"The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the
ALSA-2022:2143 advisory.

  - A privilege escalation flaw was found in Podman. This flaw allows an attacker to publish a malicious image
    to a public registry. Once this image is downloaded by a potential victim, the vulnerability is triggered
    after a user runs the 'podman top' command. This action gives the attacker access to the host filesystem,
    leading to information disclosure or denial of service. (CVE-2022-1227)

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