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: 65 on a distribution build — the fix may be backported (openssh 5.5p1). See them
Not counted: 3 only affect another platform (http_server 2.2.16, php 5.4.45). See them
Not a Tor relay, not a VPN or privacy relay address, and not on a current public blocklist.

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.
