Title:	Huawei EulerOS: Security Advisory for qemu (EulerOS-SA-2023-1212)
Summary:	The remote host is missing an update for the Huawei EulerOS 'qemu' package(s) announced via the EulerOS-SA-2023-1212 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'qemu' package(s) announced via the EulerOS-SA-2023-1212 advisory. Vulnerability Insight: A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.(CVE-2022-0216) A heap buffer overflow was found in the floppy disk emulator of QEMU. It could occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in DoS scenario, or potential information leakage from the host memory.(CVE-2021-3507) An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.(CVE-2020-14394) 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) Affected Software/OS: 'qemu' package(s) on Huawei EulerOS Virtualization release 2.9.1. Solution: Please install the updated package(s). CVSS Score: 3.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:N/A:P
