Vulnerability Title
Docker: `PUT /containers/{id}/archive` executes container binary on the host
Source: NVD (National Vulnerability Database)
Vulnerability Description
Moby is an open source container framework. In versions prior to 29.5.1 and in moby/moby v2 prior to v2.0.0-beta.14, when a compressed archive is uploaded to a container via `PUT /containers/{id}/archive` or piped through `docker cp -`, the daemon resolves decompression binaries (such as `xz` or `unpigz`) from the container's filesystem rather than the host's due to incorrect ordering of operations. A malicious container image containing a trojanized decompression binary can achieve arbitrary code execution with full daemon privileges, including host root UID and unrestricted capabilities, when a user uploads a compressed (xz or gzip) archive into that container. This issue is fixed in Docker Engine 29.5.1 and moby/moby v2.0.0-beta.14. Workarounds include only running containers from trusted images, using authorization plugins to restrict access to the `PUT /containers/{id}/archive` endpoint, and avoiding piping compressed archives into containers created from untrusted images

Moby 代码问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Moby是Moby开源的一个开源项目。旨在推动软件的容器化，并帮助生态系统使容器技术主流化。 Moby v2.0.0-beta.14之前版本存在代码问题漏洞，该漏洞源于解压操作顺序错误，导致守护进程从容器文件系统而非主机解析解压二进制文件，可能导致恶意容器镜像包含特洛伊木马化的解压二进制文件，当用户上传压缩归档文件到容器时，实现具有完整守护进程权限的任意代码执行。
