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 •

Nitro Pro before 13.2 creates a debug.log file in the directory where a .pdf file is located, if the .pdf document was produced by an OCR operation on the JPEG output of a scanner. Reportedly, this can have a security risk if debug.log is later edited and then executed. Nitro Pro versiones anteriores a 13.2, crea un archivo debug.log en el directorio donde se encuentra un archivo .pdf, si el documento .pdf fue producido por una operación OCR en la salida JPEG de un escáner. Según se reporta, esto puede tener un riesgo de seguridad si debug.log es entonces editado y luego ejecutado. • https://a-man-in-the-cookie.blogspot.com/2019/11/nitro-pro-vulnerability.html • CWE-732: Incorrect Permission Assignment for Critical Resource •
