Description

When processing project files in Omron CX-Supervisor Versions 3.4.1.0 and prior, the application fails to check if it is referencing freed memory, which may allow an attacker to execute code under the context of the application.

• CWE-416Use After FreeThe 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
