Networkupstools project reports:

NUT server (upsd), from versions 2.4.0 to 2.6.3, are exposed to crashes when receiving random data from the network.

This issue is related to the way NUT parses characters, especially from the network. Non printable characters were missed from strings operation (such as strlen), but still copied to the buffer, causing an overflow.
