Descriptions

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.

Se presenta una vulnerabilidad de escritura fuera de límites cuando es leído un archivo DGN usando Open Design Alliance Drawings SDK versiones anteriores a 2022.11. El problema específico es presentado en el análisis de los archivos DGN. Los datos diseñados en un archivo DGN y una falta de comprobación apropiada de los datos de entrada 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
