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&action=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: - 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 #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. -- You are receiving this mail because: You are the assignee for the bug.
