CVEs by severity: CRITICAL 2 HIGH 9 MEDIUM 14 LOW 11

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: 82 on a distribution build — the fix may be backported (mariadb 10.1.26, openssh 7.4p1). See them

Not counted: 1 only affects another platform (mariadb 10.1.26). 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 (82)

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.
