I have been using a wrapper around gs that sets both -P- -dSAFER.
That seems to work fine for viewing PS files, but does NOT allow
gv to work for PDFs: the (first?) invoked gs cannot have either of
those "security options" when attempting "gv some.pdf".
As with PS files, "gv /tmp/some.pdf" first does "chdir /tmp" then
invokes gs, which is rather unsafe without -P-.
I slightly wonder about the writing of the tmp file
open("/tmp/gv_random_some.pdf.tmp", O_WRONLY|O_CREAT|O_TRUNC, 0666)
from within gs (no O_EXCL so would follow a symlink allowing clobber).
Cheers, Paul
