ZoneMinder 1.23.3 on Gentoo Linux uses 0644 permissions for /etc/zm.conf, which allows local users to obtain the database username and password by reading this file.

ZoneMinder 1.23.3 on Fedora 10 sets the ownership of /etc/zm.conf to the apache user account, and sets the permissions to 0600, which makes it easier for remote attackers to modify this file by accessing it through a (1) PHP or (2) CGI script.
