Yes, that's what a memory-leak is. The question is rather if that makes
*every* leak a security problem and if not, which are and which aren't?

The difficulty lies in that grey area between "all" and "none".

curl is a fairly known project that is extremely widely used with lots of
people looking at it. Lots of people report found security issues in curl and
lots of companies and researches would LOVE to get a CVE registered against
curl with their name in it.

We can't ignore these researchers. They come to us with reports and claims. We
need to respond and we need to have a sensible consistent approach based on a
solid foundation of good logic and engineering.
