Ubuntu's Secure Boot support vulnerability threatens even Windows PCs
Ubuntu is thwarting Microsoft’s efforts to keep PCs safe. Modern Windows PCs are required to ship with Secure Boot enabled, a safety measure that limits access to Microsoft-approved operating systems. To make life easier for Linux users, Microsoft provides Linux distribution bootloaders with a Microsoft signing key. But Ubuntu’s signed bootloader will happily boot unsigned code, breaking the whole chain of trust. Thankfully, this is set to change with the upcoming Ubuntu 16.04 LTS.
