+        This is a real but theoretical unaligned read.  It might happen only on

+        arti binary.  The bad crate is depended on by env-logger and clap.
+        This is being discussed by those crates' contributors here:

+        This is an API vulnerability in ed25519-dalek v1.x.x, to the

+        keys as a single keypair.
+
+        We have desigend our APIs to work around this, and believe we
+        are not affected.  We should eventually upgrade to
+        ed25519-dalek >= 2, however.

+        This is a DOS vulnerability against rustls-webpki (only some versions)
+        and webpki (all versions) where some cert chains can cause
+        ridiculous CPU usage.
+
+        We've upgraded our rustls-webpki usage, but webpki (which is
+        unmaintained) is still used by tls-api, which we use from
+        arti-hyper.
+
+        I've opened https://github.com/stepancheg/rust-tls-api/issues/45
+        for this issue, but I'm not sure whether `tls-api` is maintained.
