binary is setuid/setgid or executed with setuid/setgid-like properties, in order
to prevent dangerous behaviors. On Linux this is determined by checking for the
AT_SECURE flag in the auxiliary vector, on the BSDs and Solaris/Illumos it is
determined by checking the issetugid syscall, and on AIX it is determined by
checking if the uid/gid match the effective uid/gid.
