This is very much correct. Additionally, since the versions in jessie and stretch are EOL upstream and the more recent development branches have diverged considerably from the older releases. Even assessing whether a particular vulnerability is present or whether a given patch addresses the vulnerability could prove quite challenging. > They are also large enough to be covered by copyright. > This is likely to be the case for any significant patch. > Consequently I believe we're not in a position to offer MongoDB security > support in LTS nor ELTS, and we need to drop it from our supported packages. > One other thing to note is that MongoDB supplies upstream-produced packages for all major distros for all supported versions of the MongoDB server. I find it unlikely that many of the users with the "mongodb" package installed from Debian sources are really using it in a way that warrants the amount of effort that is likely to be required to continue support. To be clear, my vote would be to drop support. Regards, -Roberto -- Roberto C. Sánchez
