Category:	Huawei EulerOS Local Security Checks
Title:	Huawei EulerOS: Security Advisory for qemu (EulerOS-SA-2022-2100)
Summary:	The remote host is missing an update for the Huawei EulerOS 'qemu' package(s) announced via the EulerOS-SA-2022-2100 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'qemu' package(s) announced via the EulerOS-SA-2022-2100 advisory. Vulnerability Insight: A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead 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 execute arbitrary code within the context of the QEMU process on the host.(CVE-2021-3750) Affected Software/OS: 'qemu' package(s) on Huawei EulerOS Virtualization release 2.10.0. Solution: Please install the updated package(s). CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
