Ubuntu 20.04 LTS / 21.04 / 21.10：Linux 内核漏洞 (USN-5208-1)

critical Nessus 插件 ID 156486

语言：

简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 20.04 LTS / 21.04 / 21.10 主机上安装的程序包受到 USN-5208-1 公告中提及的多个漏洞的影响。

 - 在版本低于 5.14.16 的 Linux 内核的 net/tipc/crypto.c 中发现一个问题。远程攻击者可利用透明进程间通信 (TIPC) 功能，进而利用未充分验证用户提供的 MSG_CRYPTO 消息类型大小这一漏洞。(CVE-2021-43267)

 - 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。

解决方案
