An update for qemu is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1733 Final 1.0 1.0 2022-07-01 Initial 2022-07-01 2022-07-01 openEuler SA Tool V1.0 2022-07-01 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 DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.(CVE-2021-3929) 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.
