It fails to verify that there is enough space remaining for the\nfixed 8-byte header of the structure.\n\nIf a server provides a DataOffset that leaves less than 8 bytes remaining,\nthe check passes, but subsequent reads of ReparseTag and ReparseDataLength\nwill occur out-of-bounds.\n\nFix this by ensuring the remaining space is at least the size of the\nreparse_data_buffer structure before accessing its fields.",
