GeoIP's database is AFAICT a binary format, which means the library
could theoretically suffer from buffer-overflows and such. If this is
indeed correct, you'd just need apache's mod-geoip, for instance, to put
your server in potential trouble.

Being strict, almost any format can be an attack vector in some way
(phishing sites are another extreme example, and obviously one we
shouldn't try to solve through the packaging system), but I somewhat
agree with Christoph that we could draw the line on packages that
perform automatic installations of binaries from external unchecked sources.
