GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

VAR-202104-1475

Vulnerability from variot - Updated: 2023-12-18 11:07

An out-of-bounds write vulnerability exists in the file-reading procedure in Open Design Alliance Drawings SDK before 2021.6 on all supported by ODA platforms in static configuration. This can allow attackers to cause a crash, potentially enabling a denial of service attack (Crash, Exit, or Restart) or possible code execution. The development kit accesses the data in .dwg and .dgn through a convenient, object-oriented API, and provides functions such as C++ API, support for repairing files, and support for .NET, JAVA, and Python development languages
