You are right that the CVE is specifically for the signature spoofing
issue. It's still not fully clear, but I think it is best to stick to
that. This is the reason I yesterday reverted my previous f6f251cff480
("Track evolution-data-server under CVE-2018-15587 and add upstream
references")[1] following the reasoning, in 34c907a0fb48[2] ("Do not
track evolution-data-server under CVE-2018-15587").

If at all, but I expect not at the moment, the issues related to
emails to appear to be encrypted issue, will recieve a CVE we can
start track those in the tracker. As well for the other source
packages if they arise.

OTOH at least some other distros seem to relate the CVE to the
secondary issues as well. But I think the strict interpetation of the
CVE assignment is as you outlined.
