Its not about being "possible to exploit" its a bout the servity of the issue by your logic we should spin media for every security issue ... >> > We shouldn't leave our users exposed if they >> > decide to use a live image, especially since I don't think it is >> > documented anywhere that "these images are unsuitable for use in a >> > production environment". >> >> There are unsuitable by their very nature of being live images. > > Why are we shipping unsuitable software then? We don't. Live media is useful for 1) installing the system 2) previewing or showcasing the system.
