Vulnerability Note VU#789121

Microsoft Whale Intelligent Application Gateway Whale Client Components 
ActiveX control stack buffer overflows

Overview

   The Microsoft Whale Intelligent Application Gateway Whale Client 
   Components ActiveX control contains multiple stack buffer overflows, 
   which can allow a remote, unauthenticated attacker to execute arbitrary 
   code on a vulnerable system.

I. Description

   Whale Communications Intelligent Application Gateway is an application 
   that provides SSL VPN functionality. The Whale Client Components, which 
   is provided by the file WhlMgr.dll, contains stack buffer overflow 
   vulnerabilities in the CheckForUpdates() and UpdateComponents() methods. 
   Note that Whale Communications is a subsidiary of Microsoft.

II. Impact

   By convincing a user to view a specially crafted HTML document (e.g., a 
   web page or an HTML email message or attachment), an attacker may be 
   able to execute arbitrary code with the privileges of the user. The 
   attacker could also cause the web browser to crash.

III. Solution

   Apply an update

   This issue is addressed in the Microsoft Intelligent Application 
   Gateway 3.7 SP2. To verify the version of the installed ActiveX control, 
   go to %windir%\Downloaded Program Files\ and check the value of the 
   Version field for Whale Client Components. If the version is less than 
   3.7, please utilize the following workarounds:

   Disable the Whale Client Components ActiveX control in Internet Explorer

   The vulnerable ActiveX control can be disabled in Internet Explorer by 
   setting the kill bit for the following CLSID:

      {8D9563A9-8D5F-459B-87F2-BA842255CB9A}

   More information about how to set the kill bit is available in Microsoft 
   Support Document 240797. Alternatively, the following text can be saved 
   as a .REG file and imported to set the kill bit for this control:

      Windows Registry Editor Version 5.00

      [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{8D9563A9-8D5F-459B-87F2-BA842255CB9A}]
      "Compatibility Flags"=dword:00000400

   Please note that setting the kill bit will break the Intelligent 
   Application Gateway functionality.

   Disable ActiveX

   Disabling ActiveX controls in the Internet Zone (or any zone used by an 
   attacker) appears to prevent exploitation of this and other ActiveX 
   vulnerabilities. Instructions for disabling ActiveX in the Internet Zone 
   can be found in the "Securing Your Web Browser" document.
