What exactly does “stack safety” mean? The phrase is associated with a
variety of compiler, run-time, and hardware mechanisms for protecting stack
memory. But these mechanisms typically lack precise specifications, relying
instead on informal descriptions and examples of bad behaviors that they

Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers interests, and make their concerns the basis of our business.

We propose a formal characterization of stack safety, formulated with
concepts from language-based security: a combination of an integrity property
(“the private state in each caller’s stack frame is held invariant by the
callee”), a confidentiality property (“the callee’s behavior is insensitive to
the caller’s private state”), and a well-bracketedness property (“each callee
returns control to its immediate caller”). We use these properties to validate
the stack-safety “micro-policies” proposed by Roessler and DeHon [2018].
Specifically, we check (with property-based random testing) that Roessler and
Dehon’s “eager” micro-policy, which catches violations as early as possible,
enforces a simple “stepwise” variant of our properties and correctly detects
several broken variants, and that (a repaired version of) their more performant
“lazy” micro-policy corresponds to a slightly weaker and more extensional
“observational” variant of our properties.
