Easy-to-exploit rooting flaw puts Linux computers at risk

The maintainers of Linux distributions are rushing to patch a privilege escalation vulnerability that's already being exploited in the wild and poses a serious risk to servers, desktops and other devices that run the OS.The vulnerability, tracked as CVE-2016-5195, has existed in the Linux kernel for the past nine years. This means that many kernel versions that are used in a variety of computers, servers, routers, embedded devices and hardware appliances are affected.The Red Hat security team describes the flaw as a "race" condition, "in the way the Linux kernel's memory subsystem handles the copy-on-write (COW) breakage of private read-only memory mappings." This allows an attacker who gains access to a limited user account to obtain root privileges and therefore take complete control over the system.To read this article in full or to leave a comment, please click here

Apple sues Amazon supplier over fake iPhone chargers

In a federal lawsuit filed this week, Apple asserted that nearly all the iPhones, chargers and cables it surreptitiously purchased from online retailer Amazon were fakes."As part of its ongoing brand protection efforts, [Apple] has purchased well over 100 iPhone devices, Apple power products, and Lightning cables sold as genuine by sellers on Amazon.com and delivered through Amazon's 'Fulfillment by Amazon' program," Apple's complaint said of a nine-month operation.

Deep dive: The Apple Watch Series 2 delivers on last year’s promise

When Apple jumped into the wearables market last year with the first Apple Watch, it delivered a device that offered a lot of promise, while at the same confusing and confounding many early adopters.App loading times were sluggish; the UI was wholly unfamiliar to longtime Apple buyers; connectivity was sometimes an issue; and fitness tracking didn't always work as it should. That didn't stop millions of buyers from plunging ahead, making the Apple Watch a modest success in a crowded wearables market.To read this article in full or to leave a comment, please click here

Tech execs tackling childhood cancer

It's been a few years since I've connected with network industry veteran Chris Lynch (See "Ex-Vertica CEO pledges to build high-speed railway for Big Data"), but when we did last talk he mainly had Big Data on his mind. Since then, he's started an early stage venture capital firm called Accomplice that indeed has invested in that field.
