CWE-400  (opens in a new tab)

How to fix?

Upgrade qemu-project/qemu to version 2.4.0 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The cpu_physical_memory_write_rom_internal function in exec.c in QEMU (aka Quick Emulator) does not properly skip MMIO regions, which allows local privileged guest users to cause a denial of service (guest crash) via unspecified vectors.
