PwnKit Vulnerability

Researches at Qualys have discovered a local privilege escalation vulnerability in all distributions of Linux. This vulnerability appears to be trivial to exploit, though it does require some level of “local” access (could potentially be used with SSH or other remote-control methods) for execution.

Proof of Concept exploits have been developed and released. Exploitation is likely at this point. Patches have been released and should be applied.
