Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Incorrect permissions are set by default for an API entry-point of a specific service, allowing a non-authenticated user to trigger a function that could reboot the CompactRIO (Driver versions prior to 20.5) remotely.
