xz-utils backdoor situation (CVE-2024-3094)

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.

A basic overview of how to manage dot-repeating in your Neovim plugin, as well as manipulate it to "force" what action is repeated.

Adding dot-repeat to your Neovim plugin

In Neovim, the . character repeats "the most recent action"; however, this is not always respected by plugin actions. Here we will explore how to build dot-repeat support directly into your plugin, bypassing the requirement of dependencies like repeat.vim.

The Basics

When some buffer-modifying action is performed, Neovim implicitly remembers the operator (e.g. d), motion (e.g. iw), and some other miscellaneous information. When the dot-repeat command is called, Neovim repeats that operator-motion combination. For example, if we type ci"text<Esc>, then we replace the inner contents of some double quotes with text, i.e. "hello world""text". Dot-repeating from here will do the same, i.e. "more samples""text".

Using operatorfunc

Frida logging hacks

Frida logging helper

For adding temporary logging to help understand behavior. For when it is impractical to use Frida to instrument Frida.

Choose one of these and copy-paste it into e.g. lib/interfaces/session.vala, then use log_event ("name='%s'", name); to log.

When something appears to be hanging, try applying: x-async-debug.patch.

Try to get replies to a particular set of tweets, recursively.
#!/usr/bin/env python
"""
Twitter's API doesn't allow you to get replies to a particular tweet. Strange
but true. But you can use Twitter's Search API to search for tweets that are
directed at a particular user, and then search through the results to see if
any are replies to a given tweet. You probably are also interested in the
replies to any replies as well, so the process is recursive. The big caveat
here is that the search API only returns results for the last 7 days. So
for idx = 1, 5 do repeat
print(1)
print(2)
print(3)
do break end -- goes to next iteration of for
print(4)
print(5)
until true end
