In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA
implementation. It occurs in the ati_cursor_define() routine while handling
MMIO write operations through the ati_mm_write() callback. A malicious
guest could abuse this flaw to crash the QEMU process, resulting in a
denial of service.
