Vulnerability Title
User input in WibuKey is used (without proper sanitization) to compute the address of a pointer, which can be exploited to let the user point to any storage, to which Windows responds with a denial of service.
Vulnerability Description
Improper validation of memory boundaries in WibuKey64.sys of WibuKey up to 6.70 for Windows can be exploited by an attacker by setting the pointers outside the scope of the program. This usually results in a denial of service, yet we cannot rule out the possibility of exploits that can cause Remote Code Execution and Privilege Escalation (since the driver runs with system privileges).
