SAP 3D Visual Enterprise Viewer, versión - 9, permite a un usuario abrir un archivo DIB manipulado recibido de fuentes no confiables, lo cual resulta en un bloqueo de la aplicación y que no esté disponible temporalmente hasta que el usuario reinicie la aplicación, esto es causado debido a una Comprobación de Entrada Inapropiada

This vulnerability allows remote attackers to execute arbitrary code on affected installations of SAP 3D Visual Enterprise Viewer. 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 DIB files. 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.
