Patch Available for "Scriptlet.typlib/Eyedog" Vulnerability

Specifically, the web page would be able to do anything on the computer
that the user could do.

Issue
=====
This issue involves two ActiveX controls, Scriptlet.typlib and Eyedog. These
controls are not in any way related to each other; their only relationship
is that both are incorrectly marked as "safe for scripting" and can
therefore be called from Internet Explorer.
- Scriptlet.typlib is a control used by developers to generate
Type Libraries for Windows Script Components. It is marked as
"safe for scripting", but should not be because it allows local
files to be created or modified. The patch removes the "safe
for scripting" marking, thereby causing IE to request confirmation
from the user before loading the control.
- Eyedog is a control used by diagnostic software in Windows. It is
marked as "safe for scripting", but should not be because it
allows registry information to be queried and machine
characteristics to be gathered. In addition, one of the control's
methods is vulnerable to a buffer overrun attack. The patch sets
the so-called "kill bit", which prevents it from loading within IE.
Affected Software Versions
==========================
- Microsoft(r) Internet Explorer 4.0 and 5.0
Patch Availability
==================
- ftp://ftp.microsoft.com/peropsys/IE/IE-Public/
Fixes/usa/Eyedog-fix/
NOTE: Circa September 7, 1999, the patch also will be available through
WindowsUpdate.
