Critical security issues in kubless containers

[dpippenger]

Kubeless uses bitnami/minideb:jessie as it's base for a number of components. Minideb is a slimmed down packaging of upstream Debian and as such they provide no additional security patching beyond what's provided by Debian upstream. Debian Jessie was EOL as of Jan 2020 and no longer receives security updates.

As a result the containers based on minideb:jessie are growing a steadily longer list of critical CVE. The recommended action would be to rebase on a supported version of minideb/debian. Stretch is an option for LTS support until 2022 and is well supported by the minideb project.

Here is an example of a current scan on function-controller:latest performed by grype. All of the other core framework components using minideb:jessie have similar results.

This is really bad why hasn't anyone started working on such a major issue, without CVE compliance no major institute would opt to use kubeless @murali-reddy @sebgoa @andresmgot @ngtuna can you assign this to someone it'd be really helpful !!
