[okular] [Bug 406269] New: pdf document with empty signature field is claimed to be signed

[Oliver Sander]

https://bugs.kde.org/show_bug.cgi?id=406269

Bug ID: 406269
   Summary: pdf document with empty signature field is claimed to
be signed
   Product: okular
   Version: unspecified
  Platform: Other
OS: Linux
Status: REPORTED
  Severity: normal
  Priority: NOR
 Component: general
  Assignee: okular-devel@kde.org
  Reporter: oliver.san...@tu-dresden.de
  Target Milestone: ---

Created attachment 119266
  --> https://bugs.kde.org/attachment.cgi?id=119266=edit
File with empty signature form field

The attached pdf file contains an empty signature field.  When opening the
file, Okular shows a blue message box claiming "This document is digitally
signed.", which is not correct.

For the same file, pdfsig shows

Digital Signature Info of: Anzeige_DM_Seite_3_empty.pdf
Unimplemented Feature (0): Unable to validate this type of signature
Signature #1:
  - Signer Certificate Common Name: (null)
  - Signer full Distinguished Name: (null)
  - Signing Time: Jan 01 1970 01:00:00
  - Signing Hash Algorithm: unknown
  - Signature Type: adbe.pkcs7.detached
  - Signature Validation: Signature has not yet been verified.
Unimplemented Feature (0): Unable to validate this type of signature
Signature #2:

  - Signing Time: Jan 01 1970 01:00:00
  - Signing Hash Algorithm: unknown
  - Signature Type: adbe.pkcs7.detached
  - Signature Validation: Signature has not yet been verified.
Unimplemented Feature (0): Unable to validate this type of signature
Signature #3:
  - Signer Certificate Common Name: (null)
  - Signer full Distinguished Name: (null)
  - Signing Time: Jan 01 1970 01:00:00
  - Signing Hash Algorithm: unknown
  - Signature Type: adbe.pkcs7.detached
  - Signature Validation: Signature has not yet been verified.

That looks dubious, too, so maybe the root cause is in poppler.

This happens with Okular from today's git master on Debian testing.

Ah, sorry for not being more explicit. Bug 348172 has the "Version Fixed In"
set to 19.04.0, i.e. you'll get that feature with the upcoming Okular version
only.

The scaling options are just below the "Force rasterization" option (i.e. under
"Options" -> "PDF Options" in the print dialog).
