In the WibuKey driver for Windows below Version 6.72, insufficient validation of user input when calculating the size of a kernel buffer could cause small amounts of data to be written outside the intended kernel buffer. This can lead to a system crash. Under unfavorable circumstances, adjacent kernel memory may be modified.
