An attacker inside the guest could use this issue to cause QEMU\nto crash, resulting in a denial of service, or possibly execute arbitrary\ncode on the host. In the default installation, when QEMU is used with\nlibvirt, attackers would be isolated by the libvirt AppArmor profile. \n(CVE-2020-17380)\n\nSergej Schumilo, Cornelius Aschermann, and Simon Wrner discovered that QEMU\nincorrectly handled USB device emulation. An attacker inside the guest\ncould use this issue to cause QEMU to crash, resulting in a denial of\nservice. (CVE-2020-25084)\n\nSergej Schumilo, Cornelius Aschermann, and Simon Wrner discovered that QEMU\nincorrectly handled SDHCI device emulation. An attacker inside the guest\ncould use this issue to cause QEMU to crash, resulting in a denial of\nservice.

An attacker inside the guest could use this issue to cause QEMU\nto crash, resulting in a denial of service. (CVE-2020-25723)\n\nGaoning Pan discovered that QEMU incorrectly handled ATI graphics device\nemulation. An attacker inside the guest could use this issue to cause QEMU\nto crash, resulting in a denial of service. This issue only affected Ubuntu\n20.04 LTS and Ubuntu 20.10.
