An iTerm2 window opens and it acts like a normal iTerm2 window. When you run 'tmux -CC', a new tmux session is created. iTerm2's tmux integration solves these problems.

For many users, a terminal multiplexer would be a great way to work, but they don't want to accept the drawbacks. Impressive work, Nachman.”Īnother user says, “Thank you, Mozilla. Also, tmux's find feature isn't as good as iTerm2's.

The only thing that changed was that iTerm got more secure. Users have appreciated both Mozilla and the iTerm2 team for the security update.Ī user commented on Hacker News, “I checked for update, installed and relaunched… and found that all my tabs were exactly as they were before, including my tab that had an ssh tunnel running. The CERT Coordination Center has pointed out that since the tmux integration cannot be disabled through configuration, the complete resolution to this vulnerability is not yet available.

TMUX ITERM2 UPGRADE

Nachman says that this is a serious vulnerability because “in some circumstances, it could allow an attacker to execute commands on your machine when you view a file or otherwise receive input they have crafted in iTerm2.” He also strongly recommended all the users to upgrade their iTerm2 to the latest 3.3.6 version. We expect the community will find many more creative examples.” Tom Ritter of Mozilla says, “Example attack vectors for this would be connecting to an attacker-controlled SSH server or commands like curl and tail -f /var/log/apache2/referer_log. Radically Open Security (ROS), the firm that conducted the audit, has ascertained that this vulnerability was present in iTerm2 for the last 7 years.Īn attacker can exploit this vulnerability ( CVE-2019-9535) by producing a malicious output to the terminal using commands on the targeted user’s computer or by remotely executing arbitrary commands with the privileges of the targeted user. Another major reason was the iTerm2’s processing of untrusted data. If you have a long-running job that you want out of the way, it can be convenient to bury its session.

TMUX ITERM2 PATCH

Mozilla and the iTerm2’s developer George Nachman have together developed and released a patch for the vulnerability in the iTerm2 version 3.3.6. Has anyone had this problem or found solutions. I'm guessing this is because iterm is relaying info back to tmux. Problem is I'm having noticeable performance problems just typing in the command line. The security vulnerability was found by a sponsored security audit conducted by the Mozilla Open Source Support Program (MOSS) which delivers security audits for open source technologies. I'm passing the -CC command to my tmux so that I get 'native' iTerm windows. iTerm 2 is one of the best terminal emulators for any platform, and the window split functionality is only part of that.Yesterday, Mozilla announced that a critical security vulnerability is present in the terminal multiplexer (tmux) integration feature in all the versions of iTerm2, the GPL-licensed terminal emulator for macOS. Even if you're not using any of tmux's window split functionality, that advantage alone is worth learning the basics of it.įinally, using both is always a good pick.

Plus you're learning a tool that can be used on every other major OS, so if you need to do command-line work on another computer you're not using a non-multiplexed terminal like an animal.Īlso, and to echo what a few other people have said, the ability to keep a command line process alive even if you log out of an ssh session is insanely handy for stuff like youtube-dl or compile jobs.

TMUX ITERM2 MAC

I spend at least as much time logged into my home Mac over ssh as I do in a terminal emulator running on the machine, and tmux just plain works better in that situation. Like a lot of command-line-vs-gui debates, a lot of what there is to recommend tmux over iTerm 2 as a solution for window splitting has to do with ssh and cross-platform compatibility.
