Descriptions

An Out-of-Bounds Read vulnerability exists when reading a DXF file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF files. Crafted data in a DXF file (an invalid dash counter in line types) can trigger a read 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 lectura 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 en el análisis de los archivos DXF. Los datos diseñados en un archivo DXF (un contador de guiones no válido en los tipos de líneas) pueden desencadenar una lectura 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 Open Design Alliance (ODA) ODAViewer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
