An update for qemu is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1772 Final 1.0 1.0 2022-07-22 Initial 2022-07-22 2022-07-22 openEuler SA Tool V1.0 2022-07-22 qemu security update An update for qemu is now available for openEuler-22.03-LTS. QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): A NULL pointer dereference issue was found in the ACPI code of QEMU. 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) A 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) An update for qemu is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
