Saw a Debian bug report about tucan and how it insecurely handles "plugin" updates (which are basically python scripts). These "plugins" are executed with the privileges of the user running tucan, and because there is no authenticity checking (plugins are not signed, doesn't look like there are any certificate checks when connecting to the update server, etc.), it's prone to MITM attacks where an attacker could basically run arbitrary code as the user running tucan. I'm not sure how popular this program is or how widely used, but this is definitely not good design.
