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 •

https://notcve.org/view.php?id=CVE-2020-35931
An issue was discovered in Foxit Reader before 10.1.1 (and before 4.1.1 on macOS) and PhantomPDF before 9.7.5 and 10.x before 10.1.1 (and before 4.1.1 on macOS). An attacker can spoof a certified PDF document via an Evil Annotation Attack because the products fail to consider a null value for a Subtype entry of the Annotation dictionary, in an incremental update. Se detectó un problema en Foxit Reader versiones anteriores a 10.1.1 (y versiones anteriores a 4.1.1 en macOS) y PhantomPDF versiones anteriores a 9.7.5 y versiones 10.x anteriores a 10.1.1 (y versiones anteriores a 4.1.1 en macOS). Un atacante puede falsificar un documento PDF certificado por medio de un Ataque de Anotación Maliciosa porque los productos no consideran un valor nulo para una entrada Subtype del diccionario Annotation, en una actualización incremental. • https://www.foxitsoftware.com/support/security-bulletins.html • CWE-754: Improper Check for Unusual or Exceptional Conditions •

CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2020-27860 – Foxit Reader XFA Template Out-Of-Bounds Write Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-27860
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 10.0.1.35811. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of XFA templates. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://www.foxitsoftware.com/support/security-bulletins.html https://www.zerodayinitiative.com/advisories/ZDI-20-1415 • CWE-787: Out-of-bounds Write •
