OpenBSD Gets Privilege Escalation
No, It's not a bug at all, it's a very VERY important feature. Applications can now be executed without an suid or sgid bit. Systrace raises the privileges for a single system call depending on the configured policy. This means that even if a program has a buffer overflow in it, you probably won't be able to open a remote shell or something to that effect by exploiting it, because calls necessary to do that should be disabled.
