Someone needs to spend the tiny amount of money and buy CANVAS Early Updates, where I believe you can get an exploit that works fine on DEP protected Windows XP SP3. I have to admit that I only personally testing Acrobat 9.0.0 instead of 9.2. I think Pablo originally wrote the exploit against 9.2 though. Something fun to verify today I guess. :> Also you'll get an exploit for Microsoft ADFS which will bypass DEP but only for 32 bit Windows for now. Most mitigations are exactly that - they add a second level of money that the attacker has to spend. It's usually wishful thinking that they provide a conversion from "exploitable" to "DoS". -dave http://www.adobe.com/support/security/advisories/apsa09-07.html """ Customers using Microsoft DEP ("Data Execution Prevention") functionality available in certain versions of Microsoft Windows are at reduced risk in the following configurations: * All versions of Adobe Reader 9 running on Windows Vista SP1 or Windows 7 * Acrobat 9.2 running on Windows Vista SP1 or Windows 7 * Acrobat and Adobe Reader 9.2 running on Windows XP SP3 * Acrobat and Adobe Reader 8.1.7 running on Windows XP SP3, Windows Vista SP1, or Windows 7 With the DEP mitigation in place, the impact of this exploit has been reduced to a Denial of Service during our testing.
