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.

// 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!!

어떤 문제가 있나요

우리의 서버로 하나의 request가 들어오면 서버는 응답을 처리하기 위해 필요한 여러 API를 호출하고 데이터를 가공하여 필요한 응답을 돌려줍니다. requset는 동시에 여러개 들어오기 때문에 우리는 request마다 어떤 작업을 수행했는지 그룹핑하여 모니터링하는 것이 필요합니다. 가장 일반적인 방법으로는 요청마다 requestID 를 생성해 할당하고 수행하는 작업마다 requestID 를 함께 기록하여 requestID 단위로 그룹핑해 확인하는 것입니다.

이러한 패턴은 Ruby on rails 나 Python Django 같은 플랫폼에서 매우 간단하게 구현할 수 있는데, 각 request는 하나의 thread에 할당되어 동기로 처리되기 때문에 requestID 와 같은 요청 정보는 thread context 에 저장하여 필요할 때 꺼내 사용하면 되기 때문입니다.

Widdershin

In the olden days, HTML was prepared by the server, and JavaScript was little more than a garnish, considered by some to have a soapy taste.

After a fashion, it was decided that sometimes our HTML is best rendered by JavaScript, running in a user's browser. While some would decry this new-found intimacy, the age of interactivity had begun.

But all was not right in the world. Somewhere along the way, we had slipped. Our pages went uncrawled by Bing, time to first meaningful paint grew faster than npm, and it became clear: something must be done.

And so it was decided that the applications first forged for the browser would also run on the server. We would render our HTML using the same logic on the server and the browser, and reap the advantages of both worlds. In a confusing series of events a name for this approach was agreed upon: Server-side rendering. What could go wrong?

In dark rooms, in hushed tones, we speak of colours.
