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: 24 on a distribution build — the fix may be backported (openssh 6.7p1). See them
Not a Tor relay, not a VPN or privacy relay address, and not on a current public blocklist.

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.
Every port that has answered a connection on this address, and when. A port is listed as open above only when a service was identified on it. Times are UTC.
