While writing with Kuza55 an article about local file inclusion advanced exploitation a very interesting code emerged on milw0rm that shows another technique that has advantages and disadvantages but is surely smart and not that well known (while documented on some papers and actually exploited in the past).
Few moments ago i was reading the Skype 1.4.118 for Linux changelog and noticed a new feature named "Auto-accept file transfers". Damn i thought, if it's by default an issue found accidentally some time ago is now fully weaponized: Skype 1.4.0.74 (probably also others) happily overwrites files without asking!
A lot of people contacted me about my post on FD. No, I have no clue of what's really going and I can happily live believing the official reports (http://heartbeat.skype.com/) on the issue. This is the complete message I posted to FD in reply to Valery Marchuk (http://lists.grok.org.uk/pipermail/full-disclosure/2007-August/065343.html):

Stefano `wisec` Di Paola has just released a new advisory IE 7 and Firefox Browsers Digest Authentication Request Splitting, basically using the user field an attacker is able to split the request injecting arbitrary chars.
From 23 to 31 December i was in Berlin for the CCC congress with other Italian security researchers and friends. We had good time enjoying Berlin, drinking beer and exchanging informations. Also Stefano Di Paola and Giorgio Fedon disclosed some Adobe Acrobat Reader bugs in a larger talk titled Subverting AJAX.
At CCC my friends Stefano Di Paola and Giorgio Fedon releades some of their latest findings, note that this is a translation in italiano of the original advisory aviable on wisec.it (http://www.wisec.it/vulns.php?page=9) that of course is in english. The advisory is focused on some specific bugs, one of these is called UXSS (Universal Cross Site Scripting) in PDF files.
This is a collection of resources on the topic. Some of these methods are not bullet proof but will help you develop some proactive security when writing new web applications and when hardening the existing ones.
