This can be exploited to trigger an integer underflow and potentially execute arbitrary code in kernel mode. 2) An error exists in the Windows kernel when processing certain data contained within executables. This can be exploited to trigger a NULL-pointer dereference and potentially execute arbitrary code in kernel mode. 3) An error in the Windows kernel when handling exceptions can be exploited to cause a system crash. SOLUTION: Apply patches.
