sysjailIMPORTANT: Due to handling semantics of user/kernel memory in concurrent environments, the sysjail tools, in inheriting from systrace(4), are vulnerable to exploitation. Details available here. Many thanks to Robert Watson for discovering these issues! Until these problems have been addressed, we do not recommend using sysjail (or any systrace(4) tools, including systrace(1)) for security purposes
