Red Hat pulls microcode update — Which, er, sounds like Red Hat has given up and, to avoid any blame, has told its customers to just get whatever firmware your CPU maker is offering. And if it works, it works, and if it makes your box fall over, uh, don't look at Red Hat.
Red Hat: We Didn't Pull CPU Microcode Update — "It's actually an encrypted, signed binary image, so we don't have the capability, even if we wanted to produce microcode. It's a binary blob that we cannot generate. The only people who can actually generate that are the CPU vendors."
Ubuntu almost ready to patch against Spectre — This week we published candidate Ubuntu kernels providing mitigation for CVE-2017-5715 and CVE-2017-5753 (ie, Spectre / Variants 1 & 2) to their respective -proposed pockets for Ubuntu 17.10 (Artful), 16.04 LTS (Xenial), and 14.04 LTS (Trusty).
