Hitachi Energy RTU500 CMU firmware flaws can disrupt ICS communications

RTU500 has a vulnerability, where high-load scenarios, such as sending GI requests at short intervals, may cause a NULL pointer dereference in the last entry of the enhanced message queue. This can cause a BCI_IEC104 fatal write error, resulting in connection interruption and restart, and ultimately a denial of service for bidirectional IEC 60870-5-104 communication.
Builds from 12.7.1 through 13.8.2 should move to 13.9.1 or named branch fixes; exploitation is not stated.
