[en] The Java platform is broadly deployed on billions of devices, from servers
and desktop workstations to consumer electronics. It was originally
designed to implement an elaborate security model, the Java sandbox, that
allows for the secure execution of code retrieved from potentially
untrusted remote machines without putting the host machine at risk.
Concretely, this sandboxing approach is used to secure the execution of
untrusted Java applications such as Java applets in the web browser.
Unfortunately, critical security bugs -- enabling a total bypass of the
sandbox -- affected every single major version of the Java platform since
its introduction. Despite major efforts to fix and revise the platform's
security mechanisms over the course of two decades, critical security
vulnerabilities are still being found.

In this work, we review the past and present of Java insecurity. Our goal
is to provide an overview of how Java platform security fails, such that we
can learn from the past mistakes. All security vulnerabilities presented
here are already known and fixed in current versions of the Java runtime,
we discuss them for educational purposes only. This case study has been
made in the hope that we gain insights that help us design better systems
in the future.
