If you only want to backport the CVE patch, this should be simple, if
you're experience somewhat in re-building Debian packages.

From my mind:

    # cd $WORKSPACE
    apt source exim4-daemon-heavy
    apt install build-depends exim4-daemon-heavy


    # chdir into to the new created exim-<version> directory
    # apply the patch (it is a one liner in src/string.c)


    # edit debian/changelog     # there exist tools for doing it, like dch
                                # take care to create a new incremented
                                # version not conflicting with further
                                # versions from Upstream


    dpkg-buildpackage -uc -us   # rebuild, do not sign anything


    cd ..


Be happy with your fresh created *deb files
