CVE-2020-27616

An out-of-bounds access flaw was found in the ati-vga emulator of the QEMU. This flaw occurs when the source and destination x y display parameters in ati2dblt have invalid values. This flaw allows a guest user or process to crash the QEMU process, resulting in a denial of service...

An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash the QEMU process on the host resulting in a denial of service.
