The stack included Linux, Java, Chromium, and MySQL. It took multiple person-years of playing whack-a-mole with dependencies to get it into production because we'd have to have conversations like:
Client: there's a CVE in the this module
Us: that's not exploitable because it's behind a configuration option that we haven't enabled
Client: somebody could turn it on
Us: even if they somehow did and nobody noticed, they would have to stand up a server inside your VPC and connect to that
Client: well what if they did that?
Us: then they'd already have root and you are hosed
Client: but the CVE
Us:
So I definitely appreciate any vendor that tries to minimize CVEs.
