RHEL 8:virt: rhel 和 virt-devel: rhel (RHSA-2023: 0432)

medium Nessus 插件 ID 170530

简介

远程 Red Hat 主机缺少 virt: rhel/virt-devel: rhel 的安全更新。

描述

远程 Redhat Enterprise Linux 8 主机上安装的程序包受到 RHSA-2023: 0432 公告中提及的漏洞的影响。

- 在 QEMU 的 QXL 显示设备仿真中发现一个越界读取缺陷。qxl_phys2virt() 函数不检查客户机物理地址指向的结构的大小,因此可能将超出条形空间的末尾读入邻近页面。恶意访客用户可利用此缺陷造成主机上的 QEMU 进程崩溃,从而导致拒绝服务情形。(CVE-2022-4144)

请注意,Nessus 尚未测试此问题,而是只依据应用程序自我报告的版本号进行判断。

解决方案

更新 RHEL virt: rhel/virt-devel: rhel 程序包,依据 RHSA-2023: 0432 中的指南。
