Linksys Cable/DSL router vulnerability

A security company called iDefense has announced that they have discovered a vulnerability in the Linksys BEFSR41 EtherFast Cable/DSL router. The vulnerability allows someone to crash the router by simply typing a URL into their browser. If remote management is turned on, then this can be done from anywhere on the internet.

Upgrading the firmware to a version newer than 1.42.7 will fix the problem.
