      "value": "An Out-of-Bounds Write vulnerability exists when reading a DGN file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DGN files. Crafted data in a DGN file and lack of proper validation of input data 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."

      "value": "Se presenta una vulnerabilidad de escritura fuera de l\u00edmites cuando es le\u00eddo un archivo DGN usando Open Design Alliance Drawings SDK versiones anteriores a 2022.11. El problema espec\u00edfico es presentado en el an\u00e1lisis de los archivos DGN. Los datos dise\u00f1ados en un archivo DGN y una falta de comprobaci\u00f3n apropiada de los datos de entrada pueden desencadenar una operaci\u00f3n de escritura m\u00e1s all\u00e1 del final de un b\u00fafer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto del proceso actual"
