Yeah, no offense but I agree with some of this. This is a list to discuss and explore the full disclosure of vulnerabilities, not auction them off, especially since it does seem to contrary to spirit of the list. This is not an opposition to people selling 0-days, frankly it doesn't bother me, I just think this really isn't the forum for it. On the other hand, though, even if you don't want to supply details for free, it is good to make people aware that serious known problems are out there.

ad, don't you think it would be a good idea if you either post your PoC with complete details otherwise do not post it. I mean from the "excel_like_hell.swf" demo, I do not see anything that one would infer. I can see that a xls file is created and on opening it (as per the demo), it makes a registry entry. Now how true is this? If you are posting no more info here they how is it going to help us otherwise what was the intent of the post? - Amit "ad () heapoverflow com" <ad () heapoverflow com> wrote: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have got many questions about the severity of the bug , you can show a demo yourself here: http://heapoverflow.com/excelol/excel_like_hell.swf ms will fixe this issue soon I'm sure, for me , job done, bye :> ad () heapoverflow com wrote:after many hours working on excel I have found a critical excel bug exploitable. This is not a stack bof nor a heap bof , a bug extremely hard to find and trigger , but it conduct excel to execute any arbitrary codes while opening a malicious .xls file. note: the bug isn't related to both excel dos that I have already published but shows similiar to a null pointer bug at a first look. much infos won't be disclosed publicly or privately and this will be transmitted to ms before the spyware loosers catch it :)I have said so this is only null pointer bugs but the way I trigger the bug might be modded for a remote code execution who know , I'm not a guru and maybe did an error triggering the flaw who knows :) but I bet many are already reasearching on this hehe, happy job!Let's go on the fast publishing :) I wont bother to message microsoft about this because they wont patch it for sure according that they can't patch fully exploitable bugs in a decent time, they do not patch IE dos (http://heapoverflow.com/IEcrash.htm), so no way tobotherthem, we should let them sleep a bit shhh ;) Bugs 1 and Bugs 2 are quite similiar but NOT, both are null pointer bugs . In bug1 you should mod a grafic's pointer to point to a bad area, and in bug 2 you should null out the size of the page name. attached are the 2 pocs, nor here are direct links http://heapoverflow.com/excelol/bug1.xls http://heapoverflow.com/excelol/bug2.xls Credits: AD [at] heapoverflow.com-----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) iQIVAwUBQ8PL5a+LRXunxpxfAQIHNw/9H6aug9gm0orJmZGIEQ7vGSdDwZkOCLMO Dw7pt6fzDFUKM3HeL3oR2gbQaPUZL57iuuY8NCKEoU3y5hiFm64nlWyGARu3ITW3 cuBVUWNpqvZzZbBU4mj9Rc5pG23Y8WrfsNRBAaJWJGjOTHacDsmn5sD0rIdwDXIP pb7pDztp6C4yPkWKN+n/Y5I73M1a8ZI+34VvOSqyMM8eGGTbcnnzF4Uz/f/rhZm9 Mm6NBgdQhSOHNqPYz5RjQtrC8O9e8/C3Zekj/YKr1jB3HOa0jiBLDALG7VIQwK/b 49e+nUK3FxQ49ygoWSvVwP0+7cFOdOVZ8Ahfd0EVCnyAkxJ04Qa+L9rF0FGSO+M6 ljg0ma93De14rHj1O+mQvRpotuUGSWJsfeBSPVLAuODZBmcp7N+AE3E2vKUwGjr5 k+FJWHs2fRxCkXb55mic+1aFdWxZvnXDmpJt1t+QTcWDl4OL6/+Ovu/fPWzg2vcQ i25RqdbsfKUnW2/QuoSrPzmgIc8s9UjIwFOj25eR0kUYMwjaugoGaYRMH0NdsSAK MwQJuVGtI4FaKLzYrPQ6m/dOyIqdH0s9cUyXrpNUWByVgMtO+pBSHp9gyCj9lVGs PfHEqYFQX2/xwJQ9QLJz+rCtATzcEjWkN2b79GOm622laRfFI0te/QJa/4BJLncp LGgvT0HVO0k= =smBn -----END PGP SIGNATURE----- _______________________________________________ Full-Disclosure - We believe in it.
