Several use after free vulnerabilities have been identified in CX-Supervisor (Versions 3.42 and prior). When processing project files, the application fails to check if it is referencing freed memory. An attacker could use a specially crafted project file to exploit and execute code under the privileges of the application.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
