HTML5 Storage Bug Can Fill Your Hard Drive 199 199

Dystopian Rebel writes "A Stanford comp-sci student has found a serious bug in Chromium, Safari, Opera, and MSIE. Feross Aboukhadijeh has demonstrated that these browsers allow unbounded local storage. 'The HTML5 Web Storage standard was developed to allow sites to store larger amounts of data (like 5-10 MB) than was previously allowed by cookies (like 4KB). ... The current limits are: 2.5 MB per origin in Google Chrome, 5 MB per origin in Mozilla Firefox and Opera, 10 MB per origin in Internet Explorer. However, what if we get clever and make lots of subdomains like 1.filldisk.com, 2.filldisk.com, 3.filldisk.com, and so on? Should each subdomain get 5MB of space? The standard says no. ... However, Chrome, Safari, and IE currently do not implement any such "affiliated site" storage limit.' Aboukhadijeh has logged the bug with Chromium and Apple, but couldn't do so for MSIE because 'the page is broken" (see http://connect.microsoft.com/IE). Oops. Firefox's implementation of HTML5 local storage is not vulnerable to this exploit."
