feed software for i386 Linux

Hi
I just tried to install Linux-Debian 2016.03.04 - Download version 1.0.18-5

I have got those warnings:

Lintian check results for /tmp/mozilla_dfld0/fr24feed_1.0.18-5_i386.deb:
E: fr24feed: control-file-has-bad-permissions conffiles 0755 != 0644
E: fr24feed: control-file-has-bad-permissions md5sums 0755 != 0644
E: fr24feed: control-file-has-bad-permissions postinst 0777 != 0755

E: fr24feed: control-file-has-bad-permissions preinst 0777 != 0755
E: fr24feed: control-file-has-bad-permissions prerm 0777 != 0755

How important are these warnings?
