This demonstrates that:

a) if CVEs are fixed with backported patches, the process must be 
*thorough* and not shotgun-ish like now. It's pointless to fix some CVEs 
and ignore the others, just because that's what automated tools like 
cve-checker reported or someone saw some mail on a mailing list.

b) it's okay to not fix low-severity CVEs until the upstream makes a new 
release. Upstream is much more competent than we are to judge that, and 
if the issue is high severity, they should make a new release anyway.

Please feel free to disagree.
