OpenVMS systems are highly resistant to buffer overflow attacks. What is one reason for this?

A.
buffer cannot grow beyond the minimum of WSDEF and MAXBUF, precluding buffer overflow
attacks

B.
consequent usage of NULL-terminated strings precludes buffer overflow attacks

C.
only users holding the VMS$BUFFER_OBJECT_USER rights identifier are allowed to use
buffers

D.
system services first ensure that the calling application has write access to the entire specified
buffer space
