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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
