I tested the POC and it works reliably, please patch fast !
Update: A PoC was made available on GitHub by a security engineer. Our post was updated to reflect this new information, along with an illustration of how the exploit works.

If you want to just reverse the order use
tac /etc/passwd
Yes "tac" is an inbuilt command :D reverse of cat @agarri.fr

Yes "tac" is an inbuilt command :D reverse of cat @agarri.fr
A little command-line trick... 🛠️ 🤓
You can use `rev` twice in order to process something from right to left. For example, in order to sort /etc/passwd by shell:
cat /etc/passwd | rev | sort | rev

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to.
No networking required. The post has a demo of a chat app communicating across unprivileged containers.

🚨 Open source supply chain attacks are exploding.
Starting today, that ends.
We’re releasing Socket Firewall — FREE, zero-config, CLI that blocks malware before it lands on your laptop or CI.
Just run:
npm i -g sfw
sfw npm install lodash
Works for: npm, yarn, pnpm, pip, uv, and cargo.
