CVE-2021-41091
CVE-2021-41091 该漏洞利用深入分析了 CVE-2021-41091 安全漏洞,并提供了如何利用漏洞利用脚本在主机上实现权限提升的分步指南。 漏洞概述 CVE-2021-41091 是 Moby(Docker 引擎)中的一个缺陷,由于权限限制不当,允许非特权 Linux 用户在数据目录(通常位于 /var/lib/docker)中遍历并执行程序。当容器包含具有扩展权限(例如 setuid)的可执行程序时,就会出现此漏洞。非特权 Linux 用户随后可以发现并执行这些程序,并且如果主机上用户的 UID 与容器内的文件所有者或组匹配,还可以修改文件。 Overlay 文件系统...

dd 在 macOS 上运行 Linux 容器——无需虚拟机。 什么是 dd? dd 在 Apple Silicon macOS 上原生运行 Linux 容器,无需虚拟机 。它底层没有 Linux 内核,也没有虚拟机监控程序:一个 JIT 会转换容器的代码,并在用户空间内处理其 Linux 系统调用 (gVisor / PRoot 一脉)。JIT 就是 客户机的 Linux 内核——命名空间、cgroup、overlay 镜像层和网络都以用户空间状态维护。它实现了 Docker Engine API ,因此普通的 docker CLI 即可驱动它。 容器的 计算 以原生 Apple...
