"The remote Mac OS X host has a version of Cisco AnyConnect Secure
Mobility Client prior to 3.1(6042). It is, therefore, affected by a
vulnerability due to insufficient validation of the type of host which
the client is connecting to. An attacker, by tricking users to connect
to a malicious host, can exploit this to force the client to render a
crafted authentication form to collect valid credentials.");
