"The remote host is running a version of the NetBT name service that
suffers from a memory disclosure problem.

An attacker could send a special packet to the remote NetBT name
service, and the reply will contain random arbitrary data from the
remote host memory.  This arbitrary data may be a fragment from the web
page the remote user is viewing, or something more serious like a POP
password or anything else.

An attacker may use this flaw to continuously 'poll' the content of the
memory of the remote host and might be able to obtain sensitive
information.");
