Vulnerabilities
Only affects another platform (1)
These CVEs need a platform this host visibly does not run (for example a flaw of the Windows build on a Linux host). 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.
