https://notcve.org/view.php?id=CVE-2021-38563
An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It mishandles situations in which an array size (derived from a /Size entry) is smaller than the maximum indirect object number, and thus there is an attempted incorrect array access (leading to a NULL pointer dereference, or out-of-bounds read or write). Se ha detectado un problema en Foxit PDF Reader versiones anteriores a 11.0.1 y en PDF Editor versiones anteriores a 11.0.1. Se manejan inapropiadamente las situaciones en las que el tamaño de un array (derivado de una entrada /Size) es menor que el número máximo de objeto indirecto, y se produce así un intento de acceso incorrecto al array (conllevando a una desreferencia del puntero NULL o una lectura o escritura fuera de los límites) • https://www.foxitsoftware.com/support/security-bulletins.php • CWE-129: Improper Validation of Array Index •

CVSS: 7.8EPSS: 1%CPEs: 4EXPL: 0CVE-2021-34837 – Foxit PDF Reader Annotation Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-34837
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.0.0.49893. 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 handling of Annotation objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://www.foxit.com/support/security-bulletins.html https://www.zerodayinitiative.com/advisories/ZDI-21-919 • CWE-416: Use After Free •
