Maintenance release of Relion® 670 series version 2.2 (2.2.3.2)

RELEASE NOTE 1MRG037427 – FEBRUARY 20, 2020

A new revision of Relion 670 series version 2.2 has been released. The new revision designation of the 670 series is 2.2.3.2.

The following has been corrected / improved in the new revision:

System and security related

Resolved critical vulnerabilities in the TCP/IP stack in VxWorks, commonly referred to as Urgent/11 vulnerabilities
Resolved Denial of Service vulnerability where IED reboots when crafted packets are sent to the IEC 61850-8-1 server
Resilience when communication client TCP window size goes to zero (During an active TCP connection session to the IED, the TCP window size goes to zero, the IED communication does not recover until a reboot is made. This is now solved and the IED server can handle TCP zero window connections.)
Improvements to time synchronization when using GTM module (The Initial blocking time of line differential protection in RED670 after a reboot is reduced when using GTM module and setting “DiffSync=GPS”)
Improvements to SFP supervision (Occasionally spurious alarms from the SFP modules were reported. A short filter is introduced to suppress these spurious alarms)
