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

49 of them on a software version from an earlier observation: a service of that kind is open now.

Not counted: 24 on a distribution build — the fix may be backported (openssh 6.7p1). See them

Not counted: 2 only affect a particular platform; this host's is not known (php 7.2.6). See them

Vulnerabilities

Distribution build — the fix may be backported (24)

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.
