Ubuntu 16.04 LTS / 18.04 LTS:Linux 内核漏洞 (USN-5094-1)

high Nessus 插件 ID 153797
全新!插件严重性现在使用 CVSS v3

计算的插件严重性默认已更新为使用 CVSS v3。没有 CVSS v3 分数的插件将回退到 CVSS v2 来计算严重性。可以在设置下拉列表中切换严重性显示首选项。

简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 16.04 LTS/18.04 LTS 主机上安装的程序包受到 USN-5094-1 公告中提及的多个漏洞的影响。

- 在 5.14-rc3 之前版本的 Linux 内核跟踪模块功能中,发现用户跟踪环形缓冲区的特定方式中缺少 CPU 资源。仅取得特权的本地用户(通过 CAP_SYS_ADMIN 功能)可利用此缺陷来耗尽资源,从而造成拒绝服务。
(CVE-2021-3679)

- 在 Linux: KVM 中发现一个问题,这是由程序对 KVM 中的 VM_IO|VM_PFNMAP vmas 处理不当造成。此问题可造成用户绕过 RO 检查,并导致页面在 VMM 和来宾机仍可访问时被释放。能够启动和控制 VM 的用户可以利用此问题读取/写入随机内存页面,并可能导致本地特权提升。(CVE-2021-22543)

- 在 powerpc 平台上 Linux 内核 5.13.5 及之前版本中,KVM 客户机操作系统用户可利用 arch/powerpc/kvm/book3s_rtas.c,通过 rtas_args.nargs,造成主机操作系统内存损坏,亦即 CID-f62f3c20647e。(CVE-2021-37576)

- 在 5.13.6 之前版本的 Linux 内核中,drivers/usb/host/max3421-hcd.c 允许实际邻近的攻击者在某些情况下,通过删除 MAX-3421 USB 设备来造成拒绝服务(释放后使用和错误)。(CVE-2021-38204)

- 在 5.13.3 之前版本的 Linux 内核中,drivers/net/ethernet/xilinx/xilinx_emaclite.c 使攻击者更容易破解 ASLR 保护机制,这是因为它会打印内核指针(即真正的 IOMEM 指针)。(CVE-2021-38205)

请注意,Nessus 尚未测试此问题,而是只依靠应用程序自我报告的版本号来判断。

解决方案

更新受影响的程序包。
