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: 31 on a distribution build — the fix may be backported (openssh 5.3). See them
Not counted: 1 only affects another platform (php 5.6.32). See them
Earlier software versions of this host and the CVEs they had are kept as its history. See the history

Vulnerabilities
Distribution build — the fix may be backported (31)
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.

CVE history
Software versions this host showed earlier, when we saw each, why it no longer applies, and the CVEs matched on it then. None of them is counted.
Port history
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.
