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 •

CVE-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 •
