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 •
