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
After initial configuration, the Ruggedcom Discovery Protocol (RCDP) is still able to write to the device under certain conditions. This could allow an attacker located in the adjacent network of the targeted device to perform unauthorized administrative actions.
