SuSe 9.1 TeTex World-Writable ls-R

I have probably missed previous conversations of this, but the following files (installed on my SuSe 9.1 as a requirement for another package or set of packages) were installed world-writable. theoretical 'cat /dev/zero > /var/lib/texmf/db/ls-R' ? One can either chattr them append-only or remove "other" write perms. I did the latter and will wait to see what I broke :) This has plagued some of the other distro's, and i believe they fixed theirs. Dunno if TeTex fixed in the CSV's, etc. /var/cache/fonts/ls-R /var/lib/texmf/db/ls-R /var/lib/texmf/ls-R
