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
A denial-of-service vulnerability exists in the Rockwell Automation PowerFlex® 527 due to improper input validation in the device. If exploited, a disruption in the CIP communication will occur and a manual restart will be required by the user to recover it.
