A use-after-free vulnerability exists in the _3MF_Importer::_handle_end_model() functionality of Prusa Research PrusaSlicer 2.2.0 and Master (commit 4b040b856). A specially crafted 3MF file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
