Untrusted search path vulnerability in uTorrent 2.0.3 and earlier allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse plugin_dll.dll, userenv.dll, shfolder.dll, dnsapi.dll, dwmapi.dll, iphlpapi.dll, dhcpcsvc.dll, dhcpcsvc6.dll, or rpcrtremote.dll that is located in the same folder as a .torrent or .btsearch file.

Stack-based buffer overflow in (1) uTorrent 1.7.7 build 8179 and earlier and (2) BitTorrent 6.0.3 build 8642 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long Created By field in a .torrent file.

The Web UI interface in (1) BitTorrent before 6.0.3 build 8642 and (2) uTorrent before 1.8beta build 10524 allows remote attackers to cause a denial of service (application crash) via an HTTP request with a malformed Range header.
