An exploitable use-after-free vulnerability in the DXF-parsing functionality in Autodesk Advance Steel 2018, Autodesk AutoCAD 2018, Autodesk AutoCAD Architecture 2018, Autodesk AutoCAD Electrical 2018, Autodesk AutoCAD Map 3D 2018, Autodesk AutoCAD Mechanical 2018, Autodesk AutoCAD MEP 2018, Autodesk AutoCAD P&ID 2018, Autodesk AutoCAD Plant 3D 2018, Autodesk AutoCAD LT 2018, and Autodesk Civil 3D 2018. A specially crafted DXF file may trigger a use-after-free, resulting in code execution.
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
