Please note that his is not an exhaustive list of the issues that may result from this AutoProtect defect.
NTFS supports multiple file streams. File system filter drivers can avail of a per stream context structure to maintain context information for a file stream, which can be used as-is or embedded in a driver-defined, per-stream context structure. When a NULL value is unexpectedly assigned to the stream context field of AutoProtect's I/O context structure, its GetDriveLetter() and initMountPoint() functions (using a pointer to the same) fail, resulting in hangs or crashes in different scenarios.
