A maliciously crafted IGS file in tbb.dll when parsed through Autodesk AutoCAD can be used in user-after-free vulnerability. This vulnerability, along with other vulnerabilities, could lead to code execution in the current process.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
