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]).
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
