The ProcessVolumeDeviceControlIrp function in Ntdriver.c in TrueCrypt 7.1a allows local users to bypass access restrictions and obtain sensitive information about arbitrary files via a (1) TC_IOCTL_OPEN_TEST or (2) TC_IOCTL_GET_SYSTEM_DRIVE_CONFIG IOCTL call.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
