    IETF X.509 Certificate Signature Collision Vulnerability:
    X.509 Certificates using the MD5 algorithm may be affected by a vulnerability that can weaken security.
    Workaround:

    We have to close this issue, but don't know how can we fix this vulnerability. Any solution or clue are welcome. Thank you.
