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.

psql: FATAL: Peer authentication failed for user “postgres” (or any user)

The connection failed because by default psql connects over UNIX sockets using peer authentication, that requires the current UNIX user to have the same user name as psql. So you will have to create the UNIX user postgres and then login as postgres or use sudo -u postgres psql database-name for accessing the database (and psql should not ask for a password).

If you cannot or do not want to create the UNIX user, like if you just want to connect to your database for ad hoc queries, forcing a socket connection using psql --host=localhost --dbname=database-name --username=postgres (as pointed out by @meyerson answer) will solve your immediate problem.

But if you intend to force password authentication over Unix sockets instead of the peer method, try changing the following pg_hba.conf* line:

Setup (Linux)

Virtualenv

It is always recommened to use virtualenv while you are doing development. virtualenv lets you create isolated development environments. It will help you not to mixup dependencies when working on more than one project on your machine.

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

	A few things to note about USSD:
	USSD is session driven. Every request we send you will contain a sessionId, and this will be maintained until that session is completed
	You will need to let the Mobile Service Provider know whether the session is complete or not. If the session is ongoing, please begin your response with CON. If this is the last response for that session, begin your response with END.
	If we get a HTTP error response (Code 40X) from your script, or a malformed response (does not begin with CON or END, we will terminate the USSD session gracefully.
