## 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
