Before the announcement went out, the tarball was downloaded from
ftp.gnu.org to 3 different machines by 2 different people, built on
all 3 machines independently, and the build verified to not have the
vulnerability which Emacs 25.3 was supposed to fix.  I think this made
the possibility of tampering negligibly small, if not strictly zero.
