I read about this vulnerability in the 2015-04-06-apache-addhandler-addtype Gentoo news item. I don't think I'm using any functionality that could expose me to the problem but I'd like to be able to say so for sure. Does the fact that I'm up-to-date with GLSAs, I don't have PHP5 in APACHE2_OPTS (I use php-fpm), along with the following (which I think is default) indicate that I'm not vulnerable?
