github.com/moby/go-archive is vulnerable to Path Traversal
78
High Risk
This Affects:
github.com/moby/go-archiveTL;DR
The Unpack, UnpackLayer, Untar/UntarUncompressed, and ApplyLayer helpers decide whether a symlink or hardlink target stays inside the destination directory using a plain string-prefix comparison on an unresolved path, instead of a check that accounts for how the operating system resolves links. A crafted archive can include links that pass this lexical check while resolving outside the intended extraction directory, creating or overwriting files elsewhere on the filesystem. The fix confines extraction path checks to resolved destinations so link targets cannot escape the intended directory.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and extract a tar archive that isn't fully trusted—directly or via a tool that bundles this library, such as Docker Engine, Docker CLI, Docker Desktop, Docker Sandboxes, or BuildKit.
