Use DD-WRT/OpenWRT for longer support life, not better security
The reason to use open source on your router isn't better security. While really boneheaded stuff like this isn't present, DD-WRT and OpenWRT don't and can't have perfect security.
What they do have over vendor software on routers is longer term support. Anyone care to bet whether the list of routers in that Netgear advisory is ALL the ones affected, or only the more recent models they have chosen to keep supporting? Netgear isn't going to put out a press release stating "we have fixes for this list of affected routers, and we will not be providing fixes for this list of slightly older routers which are also affected."
