Buffer overflow in the "create torrent dialog" functionality in uTorrent 1.8.3 build 15772, and possibly other versions before 1.8.3 (Build 16010), allows user-assisted remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a text file containing a large string. NOTE: some of these details are obtained from third party information.
