Updated

In GetSharedMemory of trustysharedmemorymanager.cc, there is a possible way to trigger an out of bounds read via sign extension of a negative buffer size due to an improper or implicit cast. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.
