Possible, version too vague to tell (2)
These CVEs were matched on a software version that names only a major release (such as “2”) or no version at all: whether the release running here is affected cannot be told. They are not counted anywhere on this site.

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.
