6/10/2023 0 Comments Terminal.app vs iterm2 for mac![]() ![]() The flaw, which is now tracked as CVE-2019-9535, has existed in iTerm2 for the past seven years and is located in the tmux integration. “MOSS selected iTerm2 for a security audit because it processes untrusted data and it is widely used, including by high-risk targets (like developers and system administrators),” Mozilla said in a blog post announcing the newly discovered vulnerability. The MOSS was created in the wake of the critical and wide-impact Heartbleed vulnerability in OpenSSL with the goal of sponsoring security audits for widely used open-source technologies. The iTerm2 app is a popular choice on macOS because it has features and allows customizations that the built-in Terminal doesn’t, which is why the Mozilla Open Source Support Program (MOSS) decided to sponsor a code audit for it. Terminal apps are commonly used by system administrators, developers and IT staff in general, including security teams, for a variety of tasks and day-to-day operations. ITerm2 is an open-source alternative to the built-in macOS Terminal app, which allows users to interact with the command-line shell. The flaw can be exploited if an attacker can force maliciously crafted data to be outputted by the terminal application, typically in response to a command issued by the user. One of the things I like most about programming is trying out new tools to make development feel smoother, and Warp does just that.A security audit sponsored by Mozilla uncovered a critical remote code execution (RCE) vulnerability in iTerm2, a popular open-source terminal app for macOS. If I had to guess, I’d say this has to do with it being written in Rust, but it just feels great to use. On top of how it looks though, it also feels quick and snappy. ![]() This can make deciphering long outputs much easier on your eyes. It also does a great job of pairing inputs with their outputs and highlighting them as you go back up your terminal history. So far, my favorite theme (there are many options) is Dracula. When I saw John using it, it immediately stuck out to me because it looks really clean. On top of the unique features Warp offers, I think it looks and feels amazing. I encourage you to download it and look around for yourself! These are the two main features I appreciate about Warp, but it is full of many others that I haven’t had the time to play around with yet. Now with Warp, I can hit tab and see previous commands I’ve run and suggestions based on common commands related to what I’ve typed. In the past, I’d find myself typing a letter of a command I want to run, hitting tab, getting the wrong autocomplete, and then having to backspace until I could get more specific. This might seem trivial to some, but it has helped out quite a few times when I have a verbose command with a typo way back at the beginning of the line.Īnother feature I enjoy is the GUI that comes along with tab completion. For one, you can click anywhere on your current command line to insert your cursor at that spot. Warp offers a few very useful editing features that make using it much easier than a traditional terminal like iTerm. Here are a couple of Warp’s features that have sold me on the terminal. I ended up on Warp’s website and decided to try it out. He told me it was a new terminal called Warp that’s built in Rust and to check it out. One day as I was pairing with my colleague John Ruble, I noticed he was using a different terminal that looked really cool. I even wrote a post about using iTerm2’s Python API to write some pretty cool scripts. ![]() I became accustomed to it and started enjoying the tool, customizing it to look just how I wanted, and I set default tabs pointed to my project’s different repos. Someone recommended it to me when I started at Atomic Object, and I just followed their lead. Like many developers, I used iTerm2 for all my terminal needs without ever questioning why. ![]()
