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.

Affected devices do not properly validate the RecordType-parameter in requests to the web interface on port 443/tcp. This could allow an authenticated remote attacker to crash the device (followed by an automatic reboot) or to execute arbitrary code on the device.
