-Subject: [PATCH] rootfs: do not permit /proc mounts to non-directories
-
-mount(2) will blindly follow symlinks, which is a problem because it
-allows a malicious container to trick runc into mounting /proc to an
-entirely different location (and thus within the attacker's control for
-a rename-exchange attack).
-
-This is just a hotfix (to "stop the bleeding"), and the more complete
-fix would be finish libpathrs and port runc to it (to avoid these types
-of attacks entirely, and defend against a variety of other /proc-related
-attacks). It can be bypased by someone having "/" be a volume controlled
-by another container.
-
-Fixes: CVE-2019-19921
