Comment 4 for bug 1780399

intel-microcode 3.20180703.2ubuntu1 recently landed in Ubuntu Cosmic. For the security fixes covered by this version, they are applied to older releases in bug 1783385.

Markus: as mentioned above, was to reapply or merge the Ubuntu-only changes into the latest Debian package before uploading it to Ubuntu. I don't know which is most up to date, but https://wiki.ubuntu.com/UbuntuDevelopment/Merging/GitWorkflow or https://wiki.ubuntu.com/UbuntuDevelopment/Merging might give you a starting point on how to deal with merges. (From what I remember, you need to provide two resulting debdiffs, one with the changes from the old Ubuntu package to the new one, and one from the Debian package to the new Ubuntu package.
