Signed PDF document attachments are stripped of their signature when scanned by Symantec Messaging Gateway Disarm feature.

Products

• Messaging Gateway

Issue/Introduction

When signed PDF attachments are scanned by Symantec Messaging Gateway with the Disarm feature enabled for PDF files, the signature data is removed.

 

Cause

The signature information is stored in a section of the PDF file that is always removed by Disarm as a normal part of processing.

Resolution

For PDF documents that are only signed and do not have any other Disarmable features, the PDF signature is removed but the document is otherwise not altered.
