As satisfied user of PDF-XChange Pro (incl. Viewer) I would like to know how far you have checked your software in this regard? Can you confirm, that you software is not exposed to this security issue?

Thanks in advance.

We have checked all available "sample" PDFs in regard this vulnerability and none of them can crash the PDF-XChange viewer and take advantage of the reported issues in the way they can with the Adobe Reader.

However - If you have any of such PDFs, please send them us and we will check asap. The secunia web site has only a general description and not actual PDFs.

We are confident however that since we are using our own JBIG codecs and do not rely on any 3rd party technology - it is extremley unlikey we can be affected in any similar manner.
