"The remote host contains a version of the 'FileView' ActiveX control
from Sky Software that is included in third-party products such as
WinZip.

The version of this ActiveX control on the remote host reportedly
exposes several methods that either can be used to execute arbitrary
code or are affected by buffer overflow vulnerabilities. If an
attacker can trick a user on the affected host into visiting a
specially crafted web page, he can leverage these issues to execute
arbitrary code on the host subject to the user's privileges.");
