do the "right thing" with mmap protections, once and for all.
...
in particular, if an object is mapped private, DO NOT grant
VM_PROT_ALL protections to it; it could be sensitive data.

From: Guido van Rooij <guido@gvr.win.tue.nl>
...
when mmapping a file, permissions are checked as it should be. When
mprotect()-ing the address range afterwards, no protection was checked
regarding the protection of the file originally opened. So
when you open /usr/bin/su RDONLY and SHARED you could afterwards change
the mmapped region to READ|WRITE. This gave the possibility to obtain
root privs obviously.
