WebMar 27, 2024 · Due to the increasing complexity, an application program may call third-party code which cannot be controlled by programmers but may contain security vulnerabilities. As a result, the users have the risk of suffering information leakage and control flow hijacking. WebApr 15, 2024 · We propose and study StkTokens: a new calling convention that provably enforces well-bracketed control flow and local state encapsulation on a capability machine. The calling convention is based on linear capabilities: a type of capabilities that are prevented from being duplicated by the hardware.
