Re: Nettle and CVE-2018-16869



Hi again

I can now tell that I have put nettle on the list of packages to fix. The reason is that gnutls28 package update depends on nettle being fixed and since it has been considered important enough to fix it is worth fixing this. I have added quite a few notes now into the security tracker.

Best regards

Hi Brian

Thank you. I think we almost always issue a DLA if it is a security issue. The only known exception, to my knowledge, is when we update packages in order to build something else, like compiler and such that do it itself not contain any security update.

I'll look a little further into this but I also think this is rather minor.

Thank you for your advice

First question: Is it worth fixing this problem? It sounds like it might
be a relatively minor issue.

If we were to proceed, I would imagine we need to update the library
first and then update the applications.

Does updating the library in the archive require a DLA? It would add a
security update, but user's won't see it until updating the
applications.

In the past I think I have been steered towards one CVE per application,
however not sure if that advice applies for this specific case.
