Debian: New cfengine packages fix arbitrary file overwriting

Javier Fernández-Sanguino Peña discovered several insecure temporary file uses in cfengine, a tool for configuring and maintaining networked machines, that can be exploited by a symlink attack to overwrite arbitrary files owned by the user executing cfengine, which is probably root. Fixed packages are available from security.debian.org .
