An issue was discovered in Open Design Alliance Drawings SDK before 2021.11. A stack-based buffer overflow vulnerability exists when the recover operation is run with malformed .DXF and .DWG files. This can allow attackers to cause a crash potentially enabling a denial of service attack (Crash, Exit, or Restart) or possible code execution.
