    [bug] Adobe Reader Fails PAdES PDF Revocation Check for OCSP Url with Port Number

    dj66224404

      If a certificate, embedded in a PDF, has a OCSP url such as

       

      http://oscp.example.com:8080/ocsp

       

      the newest Adobe Reader fails the revocation check and states:

       

      "An attempt was made to determine whether the certificate is valid by doing a revocation check using the Online Certificate Status Protocol (OCSP).

       

      Click Problems to view the problems that were encountered while performing this revocation check."

       

      Manual verification of the same certificate or PDF validation with other tools succeed, confirming the bug in Adobe Reader. Trying to report the bug, report states:

       

      "I would like to inform you that Adobe reader is  a free product and support for your version of the product is available only through Forums."
