Ubuntu 18.04 LTS / 20.04 LTS:Linux 内核漏洞 (USN-5210-1)

high Nessus 插件 ID 156481

简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 18.04 LTS/20.04 LTS 主机上安装的程序包受到 USN-5210-1 公告中提及的多个漏洞的影响。

- 5.8.13 之前的 Linux 内核未正确强制执行安全启动禁止签名数据库 (aka dbx) 保护机制。这会影响 certs/blacklist.c and certs/system_keyring.c。
(CVE-2020-26541)

- Linux 内核中发现缺陷。NFC 堆栈中存在一个释放后使用漏洞,可对机密性、完整性和系统可用性造成威胁。(CVE-2021-3760)

- 在用户使用 OverlayFS 以特定方式重命名的方式中,发现访问 Linux 内核 OverlayFS 子系统中的文件对象时存在争用条件。本地用户可利用此缺陷导致系统崩溃。
(CVE-2021-20321)

- 在 5.14.12 之前版本的 Linux 内核中,kernel/bpf/stackmap.c 中的 prealloc_elems_and_freelist 允许非特权用户触发 eBPF 乘法整数溢出,从而导致越界写入。(CVE-2021-41864)

- 在版本低于 5.14.15 的 PowerPC 的 Linux 内核中发现一个问题。当主机在 Power8 上运行时,恶意 KVM 客户机可利用此漏洞,造成主机崩溃,这是 SRR1 寄存器值处理中存在 arch/powerpc/kvm/book3s_hv_rmhandlers.S 实现错误所致。(CVE-2021-43056)

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
