dosfstools: Off-by-2 error leading to corruption in FAT12

The set_fat function in fat.c in dosfstools before 4.0 might allow attackers to corrupt a FAT12 filesystem or cause a denial of service (invalid memory read and crash) by writing an odd number of clusters to the third to last entry on a FAT12 filesystem, which triggers an "off-by-two error."

dosfstools: Heap-buffer-overflows in read_fat() and get_fat() functions
