A malicious, privileged user within the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.(CVE-2021-4158)\n\nA flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This issue allows a malicious user to trigger CVE-2018-13405 to obtain sensitive information or potentially escalate their privileges on the system.(CVE-2022-0358)","modified":"2026-03-11T06:20:08.539163Z","published":"2022-07-22T11:04:01Z","upstream":["CVE-2021-4158","CVE-2022-0358"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2022-1772"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-4158"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-0358"}],"affected":[{"package":{"name":"qemu","ecosystem":"openEuler:22.03-LTS","purl":"pkg:rpm/openEuler/qemu&distro=openEuler-22.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-43.oe2203"}]}],"ecosystem_specific":{"x86_64":["qemu-debugsource-6.2.0-43.oe2203.x86_64.rpm","qemu-img-6.2.0-43.oe2203.x86_64.rpm","qemu-debuginfo-6.2.0-43.oe2203.x86_64.rpm","qemu-6.2.0-43.oe2203.x86_64.rpm","qemu-hw-usb-host-6.2.0-43.oe2203.x86_64.rpm","qemu-system-aarch64-6.2.0-43.oe2203.x86_64.rpm","qemu-seabios-6.2.0-43.oe2203.x86_64.rpm","qemu-system-x86_64-6.2.0-43.oe2203.x86_64.rpm","qemu-block-curl-6.2.0-43.oe2203.x86_64.rpm","qemu-block-rbd-6.2.0-43.oe2203.x86_64.rpm","qemu-system-arm-6.2.0-43.oe2203.x86_64.rpm","qemu-block-ssh-6.2.0-43.oe2203.x86_64.rpm","qemu-block-iscsi-6.2.0-43.oe2203.x86_64.rpm","qemu-system-riscv-6.2.0-43.oe2203.x86_64.rpm","qemu-guest-agent-6.2.0-43.oe2203.x86_64.rpm"],"noarch":["qemu-help-6.2.0-43.oe2203.noarch.rpm"],"aarch64":["qemu-block-iscsi-6.2.0-43.oe2203.aarch64.rpm","qemu-block-curl-6.2.0-43.oe2203.aarch64.rpm","qemu-block-rbd-6.2.0-43.oe2203.aarch64.rpm","qemu-system-aarch64-6.2.0-43.oe2203.aarch64.rpm","qemu-img-6.2.0-43.oe2203.aarch64.rpm","qemu-system-x86_64-6.2.0-43.oe2203.aarch64.rpm","qemu-block-ssh-6.2.0-43.oe2203.aarch64.rpm","qemu-6.2.0-43.oe2203.aarch64.rpm","qemu-debugsource-6.2.0-43.oe2203.aarch64.rpm","qemu-system-arm-6.2.0-43.oe2203.aarch64.rpm","qemu-guest-agent-6.2.0-43.oe2203.aarch64.rpm","qemu-hw-usb-host-6.2.0-43.oe2203.aarch64.rpm","qemu-debuginfo-6.2.0-43.oe2203.aarch64.rpm","qemu-system-riscv-6.2.0-43.oe2203.aarch64.rpm"],"src":["qemu-6.2.0-43.oe2203.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2022-1772.json"}}],"schema_version":"1.7.5"}
