I think this might be an issue of how you're parsing the statement. It sounds like you're reading this as the exploit being available on those systems. However, when I read the line, I interpret as "xz Utils ... [is] available on almost all installations of Linux and other Unix-like operating systems," which is true. That does not necessarily suggest that they're all affected by the vulnerability. Eric
