Dear Reader,

A new revision of Switchsync PWC600 version 1.0 has been released. The new revision designation is 1.0.1.4, wherein the following items have been corrected/improved over revision 1.0.1.3.

System and security related

• Resolved critical vulnerabilities in the TCP/IP stack of 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.

Application related

• Improvements to circuit breaker operation time learning function CBLEARN

- Setting AvgSetSel = “setOPisCalcAvgValues” with no learned values present will not cause IED reboot. Instead, the function will publish the setting values.

- IED startup will no more raise a mechanical monitoring alarm.

- Clearing of fingerprint records will no more raise a mechanical monitoring alarm.

Recommendation to update

We recommend users who have faced any of the issues mentioned above to update to this release.
