Not counted: 33 on a distribution build — the fix may be backported (http_server 2.4.37, openssl 1.1.1k). See them

Not counted: 6 only affect another platform (http_server 2.4.37, php 7.2.24). See them

Vulnerabilities

Distribution build — the fix may be backported (33)

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. 2 of them are known to be exploited.
