简介
远程 Rocky Linux 主机缺少一个或多个安全更新。描述
远程 Rocky Linux 8 主机上存在安装的程序包该程序包受到公告 RLSA-2022:5821 中提及的多个漏洞的影响。- 在 QEMU 的 QXL 显示设备仿真中发现一个缺陷。cursor_alloc() 函数中的整数溢出可导致分配小光标对象，随后导致基于堆的缓冲区溢出。恶意特权客户机用户可利用此缺陷造成主机上的 QEMU 进程崩溃，或可能在 QEMU 进程环境中执行任意代码。(CVE-2021-4206)
- 在 QEMU 的 QXL 显示设备仿真中发现一个缺陷。双重提取客户机控制的值 `cursor->header.width` 和 `cursor->header.height` 可导致分配小型光标对象，随后导致基于堆的缓冲区溢出。恶意特权客户机用户可利用此缺陷造成主机上的 QEMU 进程崩溃，或可能在 QEMU 进程环境中执行任意代码。(CVE-2021-4207)
- 在 QEMU 的 virtio-net 设备中发现一个缺陷。修复 CVE-2021-3748时无意间引入了此缺陷，该缺陷在出错时忘记取消映射缓存的 virtqueue 元素，从而导致内存泄漏和其他意外结果。受影响的 QEMU 版本：6.2.0。(CVE-2022-26353)
- 在 QEMU 的 vhost-vsock 设备中发现一个缺陷。如果出错，无效元素无法在释放内存前从 virtqueue 分离，从而导致内存泄漏和其他意外结果。
QEMU 6.2.0 及更低版本会受到影响。(CVE-2022-26354)
请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。
