A match is an indication, not proof: it is based on the software version a service reported, and fixes are often backported without changing the version. See the list
Not counted: 13 on a distribution build — the fix may be backported (openssh 7.9p1). See them

Vulnerabilities
Distribution build — the fix may be backported (13)
These CVEs were matched on software built by an operating-system distribution whose package revision the service does not show. Distributions often fix a flaw without changing the upstream version number, so whether this build is affected cannot be told from its version. They are not counted.
