gnome-shell 3.22 through 3.24.1 mishandles extensions that fail to reload,
which can lead to leaving extensions enabled in the lock screen. With these
extensions, a bystander could launch applications (but not interact with
them), see information from the extensions (e.g., what applications you
have opened or what music you were playing), or even execute arbitrary
commands. It all depends on what extensions a user has enabled. The problem
is caused by lack of exception handling in js/ui/extensionSystem.js.
