Dde to incorrect use of a default URL, `singularity` action commands
(`run`/`shell`/`exec`) specifying a container using a `library://` URI
will always attempt to retrieve the container from the default remote
endpoint (`cloud.sylabs.io`) rather than the configured remote endpoint.
An attacker may be able to push a malicious container to the default
remote endpoint with a URI that is identical to the URI used by a victim
with a non-default remote endpoint, thus executing the malicious container.
Only action commands (`run`/`shell`/`exec`) against `library://` URIs are
affected. Other commands such as `pull` / `push` respect the configured
remote endpoint. (CVE-2021-32635)
If a Content-Type header changed between two pulls of the same digest, a
client may interpret the resulting content differently. (CVE-2021-41190)");
