    "summary": "### Summary During checkout, gitoxide does not verify that paths point to locations in the working tree. A specially crafted repository can, when cloned, place new files anywhere writable by the application. ### Details Although `gix-worktree-state` checks for collisions with existing files, it does not itself check if a path is really in the working tree when performing a checkout, nor do the path checks in `gix-fs` and `gix-worktree` prevent this. Cloning an untrusted repository containing specially crafted tree or blob names will create new files outside the repository, or inside the repository or a submodule's `.git` directory. The simplest cases are: - A tree named `..` to traverse upward. This facilitates arbitrary code execution because files can be placed in one or more locations where they are likely to be executed soon. - A tree named `.git` to enter a `.git` directory. This facilitates arbitrary code execution because hooks can be installed. A number of alternatives that achieve the same effect are also possible, some of which correspond to specific vulnerabilities that have affected Git in the past: - A tree or blob whose name contains one or more `/`, to traverse upward or downward. For example, even without containing any tree named `..` or `.git`, a repository can represent a file named `../outside` or `.git/hooks/pre-commit`. This is distinct from the more intuitive case a repository containing trees that represent those paths. - In Windows, a tree or blob who",
