DescriptionMetrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections. The statsd protocol (and extensions) allow mutiple metrics,separated by newlines, to be sent per packet. The send method does not validate the contents of the metric names or values. If the names have newlines and statsd control characters (colon, pipe) then metric injections are possible. Version 0.04 fixed this by modifying the _make method to block metric names with characters below ASCII 32 (which includes the newline), or colons or pipes.
