Re: Sources: Full and Partial Coverage



Hi,

No, not really. By definition CVE is the best effort project. It is so
because we rely on others (i.e., vendors, researches) to provide the information.
Until we have vendors comitted assigning CVE themselves that will continue
to be so.

Estimating how many vulnerabilities are not covered can also be questioned.
Some vendors may quietly fix things and never admitting that fact. Would
you count that as lack of coverage? I would _if_ I manage to establish that
this really happened. What are other ways that vulnerability may 'escape'?

The bottom line is that I am a pragmatist and will take what there is available
to get the job done. If we cannot reliably estimate coverage I would still
use CVE.

There are no insolvable problems. 
The question is can you accept the solution?
