Tilman Hausherr created PDFBOX-4466:
---------------------------------------
Summary: Signature without /Type /Sig can't be read
Key: PDFBOX-4466
URL: https://issues.apache.org/jira/browse/PDFBOX-4466
Project: PDFBox
Issue Type: Bug
Components: Crypto, Signing
Affects Versions: 2.0.13, 1.8.16
Reporter: Tilman Hausherr
Assignee: Tilman Hausherr
Fix For: 1.8.17, 2.0.14, 3.0.0 PDFBox
Signatures are not to be decrypted, and currently decryption is skipped when
their type is detected. However the type is optional, so in the attached file
where the type is missing it is "decrypted". See at the end of PDFBOX-4453 and
in the linked issue of the European commission DSS project. Thanks [~mkl] for
pointing me to this one.
