Luigi Auriemma has discovered a vulnerability in uTorrent, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the handling of HTTP requests and can be exploited to cause the application to crash by sending multiple HTTP requests with an overly-long "Range" header string.
Successful exploitation requires that the Web UI interface is enabled (not default).
The vulnerability is confirmed in version 1.7.6 (build 7859) on Windows. Other versions may also be affected.
