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: 79 on a distribution build — the fix may be backported (http_server 2.0.52). See them

Not counted: 1 only affects a particular platform; this host's is not known (openssh 3.9p1). See them

Not counted: 7 only affect another platform (php 4.3.9, http_server 2.0.52). See them

Vulnerabilities

Distribution build — the fix may be backported (79)

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.
