[Bug 2037516] Re: glibc: CVE-2023-5156: Memory leak in getaddrinfo after fix for CVE-2023-4806

[Daniel Black]

The CVE status on https://ubuntu.com/security/CVE-2023-5156 for most
Ubuntu Distos is "Deferred" however according to
https://git.launchpad.net/ubuntu-cve-tracker/tree/README#n352-
"Deferred" says the "package is vulnerable".

As a result of this vulnerable indicator, all ubuntu (non-manic) based
container images are being reported as vulnerable on Docker Scout.

e.g.: top CVE on
https://hub.docker.com/layers/library/mariadb/latest/images/sha256-7c58576f7e85def1dab9bf216d2de666c72e724aa4a7cf8c8cd5f1f0935827aa?context=explore


A "not-affected" affected classification would be more appropriate.
