Memory space breach — Accomplished via stack overflow, buffer overrun, or heap error, enables execution of arbitrary code supplied by the attacker with the permissions of the host process.

内存空间缺口——通过栈溢出、缓冲区溢出或堆错误来实现，以宿主进程的权限执行攻击者提供的任何代码。

Those objects can be allocated directly on the stack (which is faster) and do not enter the heap or require inspection or removal by the normal garbage collector (which reduces GC).

这样，我们就可以直接在栈上为这些对象开辟内存空间（这么做更快），无需使用堆，也不必使用常规的GC手段进行对象检测与移除了（这么做会降低GC的次数，进而提升效率）。
