FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

Background

mkfifo /tmp/gfifo

./xdp-screen-cast-ffmpeg.py &  # or run in another terminal
# Note the gstreamer pipeline
# 'pipewiresrc fd=%d path=%u ! videorate ! video/x-raw,framerate=60/1 ! videoconvert ! filesink location=/tmp/gfifo'
# I specified a 60/1 frameerate. You can do other pre-processing here, or offload it to ffmpeg.

# Encode the stream and pipe to netcat
# note: must specify correct resolution here
# we can now use h264_nvenc, mpegts, and anything else ffmpeg has

// I'm tired of extensions that automatically:
// - show welcome pages / walkthroughs
// - show release notes
// - send telemetry
// - recommend things
//
// This disables all of that stuff.
// If you have more config, leave a comment so I can add it!!
