component included with Symantec Winfax Pro and installed on the
remote Windows host, reportedly contains a stack-based buffer overflow
that can be triggered by calling the 'AppendFax' method with an overly
long argument.  If an attacker can trick a user on the affected host
into viewing a specially crafted HTML document, he can leverage this
issue to execute arbitrary code on the affected system subject to the
user's privileges."  );
