A maliciously crafted DWF, 3DS and DWFX files in Autodesk AutoCAD 2022, 2021, 2020, 2019 can be used to trigger use-after-free vulnerability. Exploitation of this vulnerability may lead to 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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
