Collectl: collectl: colmux does not sanitize ansi/vt100 terminal escape sequences in data received from remote collectl instances
colmux in collectl before 4.3.20.2 does not sanitize ANSI/VT100 terminal escape sequences in data received from remote collectl instances before displaying it, allowing a local user on a monitored host to inject escape sequences into the terminal of an operator running colmux, via a crafted process name (argv[0]).
