guest could possibly use this issue to leak host\nmemory to obtain sensitive information. This issue only affected Ubuntu\n18.04 LTS. (CVE-2020-10756)\n\nEric Blake and Xueqiang Wei discovered that the QEMU NDB implementation\nincorrectly handled certain requests. A remote attacker could possibly use\nthis issue to cause QEMU to crash, resulting in a denial of service. This\nissue only affected Ubuntu 20.04 LTS. (CVE-2020-10761)\n\nZiming Zhang discovered that the QEMU SM501 graphics driver incorrectly\nhandled certain operations. An attacker inside a guest could use this issue\nto cause QEMU to crash, resulting in a denial of service, or possibly\nexecute arbitrary code. (CVE-2020-12829)\n\nIt was discovered that the QEMU SD memory card implementation incorrectly\nhandled certain memory operations. An attacker inside a guest could\npossibly use this issue to cause QEMU to crash, resulting in a denial of\nservice.
