CFPDF doesn't work with protected files after ColdFusion 2016 update

Report · Sep 13, 2019

Hello,

We have updated our CentOS ColdFusion 2016, from update 8 to update 11. Installation was successful, and the installation log shows 0 errors.

After that, one of our scripts, that generates a thumbnail from a password protected PDF, has stopped working.

Our code is

<cfpdf action="thumbnail" source="#data.filename#" password="mypassword" destination="#sPathTemp#" pages="1" scale="30" format="jpeg" resolution="high" overwrite="Yes">

and the error is

An error occurred during THUMBNAIL operation in &lt;CFPDF&gt;. Error: The password provided is either wrong or does not have sufficient permission to perform this action. <br>The error occurred on line 1.

in more detail

coldfusion.pdf.PDFDocOperation$PDFUnAuthorisedOperationException: An error occurred during THUMBNAIL operation in &lt;CFPDF&gt;. at coldfusion.pdf.PDFDocHandler._extractSinglePDFImages(PDFDocHandler.java:4264) at coldfusion.pdf.PDFDocHandler._extractImages(PDFDocHandler.java:4177) at coldfusion.pdf.PDFDocHandler.extractImages(PDFDocHandler.java:4073) at coldfusion.pdf.PDFDocOperation.thumbnail(PDFDocOperation.java:2965) at coldfusion.tagext.lang.PDFTag.doEndTag(PDFTag.java:1990) at coldfusion.runtime.CfJspPage._emptyTcfTag(CfJspPage.java:3708)

The password is, of course, correct, and thumbnail generation worked just fine before the update. After some forum digging, we have installed the Java Cryptography Extension (https://www.oracle.com/technetwork/es/java/javase/downloads/jce-7-download-432124.html), to no avail.

We currently coded a imagemagik-based workaround, but we would like to continue working with cfpdf. Any clue?

TIA,
