(International Business Times) Google and security firm Red Hat have discovered a critical security flaw in the Internet's Domain Name System (DNS) that affects a library in a universally used protocol. This means an attacker could use it to infect almost everything on the entire internet. With the flawed code spread far and wide, it will likely take years of effort to patch the bug.
Google engineers and Red Hat researchers both independently discovered the DNS bug within the GNU C standard library (glibc) called CVE-2015-7547, and then worked together to create a patch. The security vulnerability works by tricking browsers into looking up suspicious domains, which causes servers to reply with DNS names that are far too long, thus causing a buffer overflow in the victim's software.
