Yifan Lu jailbreaks Kindle Touch, uses a special MP3 file to do so

We've seen a fair share of Kindle Jailbreaks over the past few years, but Yifan Lu's (evidently the first) for the Kindle Touch is certainly novel in its approach. As The Digital Reader points out, a sizeable chunk of the Touch's software is essentially a string of pseudo HTML5 and JavaScript webpages -- differentiating it from Kindles prior -- which led Lu to notice an exploit rooted in its browser. It's there where he found a function titlednativeBridge.dbgCmd(), which'll run any ol' shell command as root. Armed with that knowledge, Lu crafted the jailbreak by cramming his payload of HTML and JavaScript into the ID3 tags of an easily downloadable MP3 file. There isn't much to be gained from "playing" that MP3 just yet, but Lu's looking forward to developers using the tools needed to write programs for the device. Full details about the jailbreak can be found at source link below, but before you head off, you can catch the video proof after the break.
