The grub_memmove function in shlr/grub/kern/misc.c in radare2 1.5.0 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file, possibly related to a read overflow in the grub_disk_read_small_real function in kern/disk.c in GNU GRUB 2.02.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
