The last time I reported a security flaw to facebook, it took around 6 weeks until they replied, telling me that there was no flaw at all. Perhaps that's why I decided to make public any flaw on facebook from now on.[cut some technical details for readability](Properly replace the <EXTREMLY LONG MESSAGE HERE> before testing) This might not be the best vulnerability description ever, but I hope it helps solving the condition as soon as possible. Have fun.What length of EXTREMELY LONG MESSAGE were you using in testing? 1K bytes, 1M, 1G?
I couldn't tell, I started up with 1,000 chars and increased 1,000 by 1,000 until 100,000 with parallel connections. But certainly, even if you only full the text input using the regular UI from facebook, you'll crash any regular box, or tablet. Perhaps you should try with 1 Gb tho and see what happens, there's test users you can create from the facebook.com/whitehat. -- Success, *forward, quick.* Chris C.
