Sure, no problem. One thing, as a first step I put new_fax into bin_t,
as this was a suggestion from sealert output.
I do think this probably does not belong to the getty policy, as mgetty,
receiving a fax, does far more than standard getty, imho.
echo "policy_module(mygetty, 1.0.0)" > mygetty.te;
echo "optional_policy(\`" >> mygetty.te;
echo "gen_require(\`" >> mygetty.te;
echo "type getty_t;" >> mygetty.te;
echo "')" >> mygetty.te;
echo "corecmd_exec_shell(getty_t)" >> mygetty.te;
echo "')" >> mygetty.te;
make -f /usr/share/selinux/devel/Makefile mygetty.pp
sudo semodule -i mygetty.pp
See if this solves your issue
