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.

Description of the Launch Constraints introduced in iOS 16
iOS 16 introduced launch constraints, which can be used to constraint the launch of an application.
There are three types of constraints:
Self Constraints, which the launched application itself must meet
Parent Constraints, which the parent process must meet
Responsible Constraints, which the "responsible process" must meet (I assume that the responsible process is the process that asked launchd to launch a service)
Additionally, the TrustCache format was updated (see below) to support assigning each binary a "Constraint Category", which forces Self and Parent Constraints.
Note that Self, Parent and Responsible Constraints can also be set by the process performing the launch and they can be included in the code signature, in the new blob type 0xFADE8181. In both cases, the constraints are DER encoded (just like the DER entitlements).
Constraint Categories (from TrustCache, new in version 2):

Download the appropriate Kali Linux .iso

I used a 64 bit .iso image, downloaded via HTTP. I downloaded the amd64 weekly version, as the pool linux headers (needed below for installation of wireless drivers) were ahead of the stable release kernel.

Download the SHA256SUMS and SHA256SUMS.gpg files from the same location.
