Heap-based buffer overflow in Foxit Reader and PhantomPDF 7.3.4.311 and earlier on Windows allows remote attackers to cause a denial of service (memory corruption and application crash) or potentially execute arbitrary code via the Bezier data in a crafted PDF file. Desbordamiento de búfer basado en memoria dinámica (heap) en Foxit Reader y PhantomPDF, en versiones 7.3.4.311 y anteriores en Windows, permite que atacantes remotos provoquen una denegación de servicio (corrupción de memoria y cierre inesperado de la aplicación) o que puedan ejecutar código arbitrario mediante datos Bezier en un archivo PDF manipulado. • https://fortiguard.com/zeroday/FG-VD-16-018 https://www.foxitsoftware.com/support/security-bulletins.php • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Foxit Reader 8.3.1.21155. 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 parsing of SOT markers. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. • https://www.foxitsoftware.com/support/security-bulletins.php https://zerodayinitiative.com/advisories/ZDI-17-856 • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
