Distribution build — the fix may be backported (6)
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. 1 of them is known to be exploited.
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.
