Google details CPU flaws, claims AMD, ARM and Intel all affected

Google has come forward to claim responsibility for discovering a pair of serious security holes in Intel processors that run almost 9 in 10 computers in the world. And worse: the company has echoed a statement by Intel yesterday that the flaws are not specific to that company’s chips. Contrary to published reports, a blog post on the Google Security Blog by Matt Linton, a Senior Security Engineer at Google and Pat Parseghian, a Technical Program Manager said that flaws dubbed “Specter” (PDF) and “Meltdown” (PDF) are not limited to chips by Intel, but exist in central processing unit (CPU) chips by a wide range of vendors including Intel, AMD and ARM. Google discovered the flaws The flaws were discovered by Jann Horn, a researcher for Google’s Project Zero security team, discovered the flaw and showed how malicious actors could game a common CPU feature known as “speculative execution” to […]

Experts Propose Standard for IoT Firmware Updates

Bleeping Computer reported that a new proposal submitted to the Internet Engineering Task Force (IETF) defines a secure framework for delivering firmware updates to Internet of Things (IoT) devices. Insecure software updates for embedded devices (aka ‘firmware’) have been a frequent source of security lapses on mobile and embedded devices like Internet connected webcams. Filed on October 30, the “IoT Firmware Update Architecture,” establishes security requirements for device makers to implement when designing firmware update mechanisms for connected devices. A familiar list of features The proposed rules include features that have long been recommended by security experts to permit safe handling of software updates. Among them the use of cryptographically signed updates and public key cryptography to provide end-to-end security and verify firmware images, as well as the ability to work with low-power and resource constrained IoT devices. Firmware has been the source of widespread security issues. For example, low-cost […]
