Bug ID: 407338 Summary: Okular segfaults when opening a file digitally signed with portablesigner and Acrobat Reader Product: okular Version: 1.7.0 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: critical Priority: NOR Component: general Assignee: okular-de...@kde.org Reporter: ang...@iac.es Target Milestone: --- Created attachment 119916 --> https://bugs.kde.org/attachment.cgi?id=119916&action=edit Digitally signed documents (one gives the segmentation fault) SUMMARY I use the code portablesigner to digitally sign a document, and Okular can read the generated document no problem (see example sample-sig.pdf attached). My colleagues, who uses ADOBE Acrobat Reader DC Version 2019.010.20099 in a Mac signs the same document, and Okular can read it no problem (see example sample_victor.pdf attached). But if he signs the file previously signed by me (so as to have it signed by both of us), then Okular segfaults when trying to open the file (see example sample_sig_victor.pdf). This might not be a problem specific to Okular, since trying to see the signatures with pdfsig (v. 0.76.1), also segfaults: [angelv@bug]$ pdfsig sample_sig_victor.pdf Digital Signature Info of: sample_sig_victor.pdf Signature #1: - Signer Certificate Common Name: DE VICENTE GARRIDO ANGEL MANUEL - 30660835H - Signer full Distinguished Name: CN=DE VICENTE GARRIDO ANGEL MANUEL - 30660835H,SN=DE VICENTE GARRIDO,givenName=ANGEL MANUEL,serialNumber=IDCES-30660835H,C=ES - Signing Time: May 08 2019 12:16:59 - Signing Hash Algorithm: SHA1 - Signature Type: adbe.pkcs7.sha1 - Signed Ranges: [0 - 13426], [18278 - 24071] - Not total document signed - Signature Validation: Signature is Valid. - Certificate Validation: Certificate is Trusted.
