A heads-up from SecuriTeam: "A security vulnerability has been confirmed in Lycos's Search Engine (other engines are suspected to be vulnerable as well).
search results displayed to the end user by Lycos. A malicious user may create an interface embedded into the engines pages (if the search engine supports PHP this is even
worse; a malicious web site can build up a shell) or start a redirect attack."
