Description:
A vulnerability was reported in Opera. A remote user can cause Opera to conduct portscans.
In response to an FTP PASV command from the target user's Opera client, the remote connected FTP server can return a port number and different IP address, causing the Opera client to connect to the specified IP address and port number.
A remote user can create a specially crafted web page that, when loaded by the target user, will cause the target user's browser to connect to a malicious FTP server and then scan the ports specified by the malicious FTP server, including scanning systems that are on the target user's internal network.
