    Multiple vulnerabilities have been discovered in QEMU. Please review the

Impact :

    A local attacker could potentially execute arbitrary code with
      privileges of QEMU process on the host, gain privileges on the host
      system, cause a Denial of Service condition, or obtain sensitive
      information.
  
Workaround :
