The default certificates are set to expire in 2017 and an IM 12.6.x bulletin was released "CA - PROACTIVE NOTIFICATION - IDMGR - ADVISORY - AIDMGR-100477" which provided instructions to follow to replace the expiring certificates for product versions of IM 12.6 SP1-SP8 but does not mention IM 12.5.x release which has already reached End Of Support.
