Rockwell Automation was made aware of a vulnerability that causes all affected controllers on the same network to result in a major nonrecoverable fault(MNRF/Assert). This vulnerability could be exploited by sending abnormal packets to the mDNS port. If exploited, the availability of the device would be compromised.
The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated.
