The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, a Signature Wrapping vulnerability exists in multiple products. An attacker can use /ByteRange and xref manipulations that are not detected by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects eXpert PDF 12 Ultimate, Expert PDF Reader, Nitro Pro, Nitro Reader, PDF Architect 6, PDF Editor 6 Pro, PDF Experte 9 Ultimate, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, PDF-XChange Editor and Viewer, Perfect PDF 10 Premium, Perfect PDF Reader, Soda PDF, and Soda PDF Desktop. • https://pdf-insecurity.org/signature/evaluation_2018.html https://pdf-insecurity.org/signature/signature.html https://www.foxitsoftware.com/support/security-bulletins.php https://www.pdfa.org/recently-identified-pdf-digital-signature-vulnerabilities • CWE-347: Improper Verification of Cryptographic Signature •

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects LibreOffice, Master PDF Editor, Nitro Pro, Nitro Reader, Nuance Power PDF Standard, PDF Editor 6 Pro, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, Perfect PDF 10 Premium, and Perfect PDF Reader. • https://pdf-insecurity.org/signature/evaluation_2018.html https://pdf-insecurity.org/signature/signature.html https://www.foxitsoftware.com/support/security-bulletins.php https://www.pdfa.org/recently-identified-pdf-digital-signature-vulnerabilities • CWE-347: Improper Verification of Cryptographic Signature •
