Unknown Unknown - Not Provided
Use of Uninitialized Variable in ODA Drawings SDK Causes Crash

Publication date: 2025-12-22

Last updated on: 2025-12-22

Assigner: Open Design Alliance

Description
A Use of Uninitialized Variable vulnerability exists in Open Design Alliance Drawings SDK static versions (mt) before 2026.12. Static object `COdaMfcAppApp theApp` may access `OdString::kEmpty` before its initialization. Due to undefined initialization order of static objects across translation units (Static Initialization Order Fiasco), the application accesses uninitialized memory. This results in application crash on startup, causing denial of service. Due to undefined behavior,  memory corruption and potential arbitrary code execution cannot be ruled out in specific exploitation scenarios.

Impact Analysis

The vulnerability can cause the application to crash on startup, resulting in a denial of service. Additionally, due to the undefined behavior, there is a risk of memory corruption and potentially arbitrary code execution in certain exploitation scenarios, which could lead to further security compromises.

Executive Summary

This vulnerability is a Use of Uninitialized Variable issue in the Open Design Alliance Drawings SDK static versions before 2026.12. Specifically, a static object named COdaMfcAppApp theApp may access OdString::kEmpty before it has been initialized. Because the order of static object initialization across different translation units is undefined (known as the Static Initialization Order Fiasco), the application ends up accessing uninitialized memory. This can cause the application to crash on startup.
