Rockwell Automation Arena Simulation Software versions 16.00.00 and earlier contain a USE AFTER FREE CWE-416. A maliciously crafted Arena file opened by an unsuspecting user may result in the application crashing or the execution of arbitrary code.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
