{"id":"USN-5489-1","summary":"qemu vulnerabilities","details":"Alexander Bulekov discovered that QEMU incorrectly handled floppy disk\nemulation. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service, or possibly leak\nsensitive information. (CVE-2021-3507)\n\nIt was discovered that QEMU incorrectly handled NVME controller emulation.\nAn attacker inside the guest could use this issue to cause QEMU to crash,\nresulting in a denial of service, or possibly execute arbitrary code. This\nissue only affected Ubuntu 22.04 LTS. (CVE-2021-3929)\n\nIt was discovered that QEMU incorrectly handled QXL display device\nemulation. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service, or possibly execute\narbitrary code. (CVE-2021-4206, CVE-2021-4207)\n\nJietao Xiao, Jinku Li, Wenbo Shen, and Nanzi Yang discovered that QEMU\nincorrectly handled the virtiofsd shared file system daemon. An attacker\ninside the guest could use this issue to create files with incorrect\nownership, possibly leading to privilege escalation. This issue only\naffected Ubuntu 22.04 LTS. (CVE-2022-0358)\n\nIt was discovered that QEMU incorrectly handled virtio-net devices. A\nprivileged attacker inside the guest could use this issue to cause QEMU to\ncrash, resulting in a denial of service, or possibly execute arbitrary\ncode. (CVE-2022-26353)\n\nIt was discovered that QEMU incorrectly handled vhost-vsock devices.
