Re: PROPOSAL: Cluster 20 - DESIGN (27 candidates)



My .02:
The presence of finger should be an entry.  So should .forward.

- Sometimes their presence is a problem, or shall we say (even though we're
having a problem with the definition) a vulnerability.
- Some tools will report this kind of thing.  That's an important factor.  We
wanted the CVE to aid interoperability.  Need reasonably broad set of entries for
that.
- These are an appropriate level of abstraction; a reasonably atomic thing.

WRT the discussion below, sure, if we go nuts we could also list A/C power,
batteries, ethernet cables, and more as vulnerabilities.  We don't have a
sufficiently precise definition of vulnerability to absolutely dictate
decisions.   So, for now formalism may not always serve us well and we need to
apply judgment, which will of course vary.  But keeping the purposes of CVE in
mind might help.  If it appears in some tools, put it in.  If some subset of the
reviewers can give good reasons something constitutes a vulnerability, put it
in.  If there is history of exploitation, put it in.

On a related note, I do, however, think our attempts at formalism regarding
distinguishing between one/many entries, etc. are useful, and needed.
