A security researcher has found multiple zero-day security vulnerabilities in Tizen, the Linux based application that's found on multiple Samsung appliances. These Samsung TV security vulnerabilities extend back for about the past two years, and there are some Samsung phone security problems as well. A few weeks ago, Wikileaks documents showed that the CIA can make a Samsung smart TV spy on its owners by installing malware via a USB memory stick. Now, it appears that this same type of malware can be installed via a Tizen Store app vulnerability. Note that this apparently has nothing to do with Linux kernel security, but rather with the app that was built around the Linux kernel.

This systemd security flaw, which was accidentally introduced in 2015, creates a DNS security flaw on affected systems. It works by allowing an attacker to perform a buffer overflow attack against an affected Linux system, which in turn would either crash the machine, or allow the attacker to perform a remote code execution attack. The referenced article indicates that the flaw is present on Ubuntu 16.10 and Ubuntu 17.04, but it would also be present on other Linux distros that use the affected versions of systemd. If you're a Linux administrator, you need to get these affected systems patched as soon as possible. Linux security after all, is very important.
