Descriptions

An Out-of-Bounds Write vulnerability exists when reading a DXF or DWG file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF and DWG files. Crafted data in a DXF or DWG file (an invalid number of properties) can trigger a write operation past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

Se presenta una vulnerabilidad de escritura fuera de límites cuando es leído un archivo DXF usando Open Design Alliance Drawings SDK versiones anteriores a 2022.11. El problema específico es presentado dentro del análisis de los archivos DXF. Los datos diseñados en un archivo DXF (un número no válido de propiedades) pueden desencadenar una operación de escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
