It's good, but it isn't enough. You stated you've got a lot of perl that writes to logfiles. Is it the only thing writing to those log files, and /are you /really/ sure/? (Yes, that was double-italics.) You need to filter any potentialy untrusted data before it gets to your terminal. That could be as simple as using less out of "raw" mode (assuming it doesn't have bugs of it's own), or piping it through tr/\e/<esc>/;, etc, etc.
