CVEs by severity: CRITICAL 3 HIGH 8 MEDIUM 4
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: 39 on a distribution build — the fix may be backported (openssh 8.0). See them
Not counted: 1 only affects another platform (php 5.6.40). See them
Not a Tor relay, not a VPN or privacy relay address, and not on a current public blocklist.
