OESA-2023-1474 (CVE-2022-1050)

Vulnerability from osv_openeuler – Published: 2023-08-06 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

qemu security update

Details

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

Security Fix(es):

A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading to a use-after-free condition.(CVE-2022-1050)

A flaw was found in the QEMU Guest Agent service for Windows. A local unprivileged user may be able to manipulate the QEMU Guest Agent's Windows installer via repair custom actions to elevate their privileges on the system.(CVE-2023-0664)

A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. The 9pfs server did not prohibit opening special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a device file in the shared folder.(CVE-2023-2861)

Severity

8.8 (High)
