Security Advisory: Misfortune Cookie Vulnerability

In December 2014, news broke of an exploit in versions of the RomPager Software called 'Misfortune Cookie' also known by the identifications CVE-2014-9222 or VU#561444. The vulnerability is contained within older but still widely used versions of RomPager, a  web server used in many common brands of router and other embedded systems.  Many millions of routers still use the vulnerable code.

The exploit itself requires that a hacker sends a malformed packet to a vulnerable router; this causes a memory corruption and in turn allows the attacker to take administrative control of your router. Once he/she has that, he controls and has access to your data (potentially both LAN and Internet traffic).
