Hardware and software makers are scrambling to determine if their wares suffer from a critical vulnerability recently discovered in third-party code libraries used by hundreds of vendors, including Netgear, Linksys, Axis, and the Gentoo embedded Linux distribution.

The flaw makes it possible for hackers with access to the connection between an affected device and the Internet to poison DNS requests used to translate domains to IP addresses, researchers from security firm Nozomi Networks said Monday. By feeding a vulnerable device fraudulent IP addresses repeatedly, the hackers can force end users to connect to malicious servers that pose as Google or another trusted site.

The vulnerability, which was disclosed to vendors in January and went public on Monday, resides in uClibc and uClibc fork uClibc-ng, both of which provide alternatives to the standard C library for embedded Linux. Nozomi said 200 vendors incorporate at least one of the libraries into wares that, according to the uClibc-ng maintainer, include the following:

Wii Sports is dead; long live Nintendo Switch Sports.

This many years into the Switch’s life span, Nintendo has finally decided that its casual, cartoony take on sports should live on, even if its original home on the Wii is no longer supported. But what’s in a name? Are the words “Nintendo” and “Sports” enough to imply a continuation of the series’ style, mechanics, and fun?

This week, we’ve learned that, on the surface level, things look and feel quite familiar. But while Nintendo Switch Sports sometimes feels cozy and accessible, there’s no getting around an unfortunate “Switch” in the series’ direction.

Disc-appointed by the sports selection

In some ways, NSS follows the trail blazed by 2006’s Wii Sports. If you’re one of roughly 82 million people who’ve played the original, you know the drill: motion controls reign in six dumbed-down, easy-to-play sports games, and players select a cartoony avatar to represent their wrist-waggling selves on their TV. If you don’t like NSS‘s touched-up avatars, you can select an old Wii-era Mii (learn how to create one on your Switch here) and transport back to 2006.
