Microsoft Windows and Internet Explorer Vulnerabilities

   Original release date: April 11, 2006
   Last revised: --
   Source: US-CERT


Systems Affected

     * Microsoft Windows
     * Microsoft Internet Explorer

   For more complete information, refer to the Microsoft Security
   Bulletin Summary for April 2006.


Overview

   Microsoft has released updates that address critical vulnerabilities
   in Microsoft Windows and Internet Explorer. Exploitation of these
   vulnerabilities could allow a remote, unauthenticated attacker to
   execute arbitrary code or cause a denial of service on a vulnerable
   system.


I. Description

   Microsoft Security Bulletin Summary for April 2006 addresses
   vulnerabilities in Microsoft Windows and Internet Explorer. Further
   information is available in the following US-CERT Vulnerability Notes:


   VU#876678 - Microsoft Internet Explorer createTextRange()
   vulnerability 

   Microsoft Internet Explorer fails to properly handle the
   createTextRange() DHTML method, possibly allowing a remote,
   unauthenticated attacker to execute arbitrary code.
   (CVE-2006-1359)


   VU#984473 - Microsoft Internet Explorer contains overflow in
   processing script action handlers 

   A vulnerability in the Microsoft Internet Explorer web browser could
   allow a remote attacker to crash the browser or possibly execute
   arbitrary code on a vulnerable system.
   (CVE-2006-1245)


   VU#434641 - Microsoft Internet Explorer may automatically execute HTA
   files 

   Microsoft Internet Explorer fails to properly handle HTA files. This
   vulnerability may allow a remote attacker to execute arbitrary code.
   (CVE-2006-1388)


   VU#503124 - Microsoft Internet Explorer fails to handle specially
   crafted, malformed HTML 

   Microsoft Internet Explorer fails to properly handle malformed HTML.
   This vulnerability may allow a remote attacker to execute arbitrary
   code on a vulnerable system.
   (CVE-2006-1185)


   VU#959049 - Multiple COM objects cause memory corruption in Microsoft
   Internet Explorer 

   Microsoft Internet Explorer allows instantiation of COM objects not
   designed for use in the browser, which may allow a remote attacker to
   execute arbitrary code or crash IE.
   (CVE-2006-1186)


   VU#824324 - Microsoft Internet Explorer fails to properly handle HTML
   elements with a specially crafted tag 

   Microsoft Internet Explorer fails to properly handle HTML element
   tags, which may allow a remote, unauthenticated attacker to execute
   arbitrary code.
   (CVE-2006-1188)


   VU#341028 - Microsoft Internet Explorer fails to properly handle
   double-byte characters in specially crafted URLs 

   Microsoft Internet Explorer fails to properly handle double-byte
   characters in URLs, which may allow a remote, unauthenticated attacker
   to execute arbitrary code.
   (CVE-2006-1189)


   VU#234812 - Microsoft Windows contains a vulnerability in the
   RDS.Dataspace ActiveX control in MDAC 

   Microsoft Windows fails to properly handle the RDS.Dataspace ActiveX
   control possibly allowing a remote attacker to execute arbitrary code.
   (CVE-2006-0003)


   VU#641460 - Microsoft Windows Explorer fails to properly handle COM
   objects 

   Microsoft Windows fails to properly handle COM Objects. This
   vulnerability may allow a remote unauthenticated attacker to execute
   arbitrary code on a vulnerable system.
   (CVE-2006-0012)


II. Impact

   A remote, unauthenticated attacker could execute arbitrary code with
   the privileges of the user. If the user is logged on with
   administrative privileges, the attacker could take complete control of
   an affected system. An attacker may also be able to cause a denial of
   service.


III. Solution

Apply Updates

   Microsoft has provided updates for these vulnerabilities in the
   Security Bulletins and on the Microsoft Update site.

Workarounds

   Please see the US-CERT Vulnerability Notes for workarounds. Many of
   these vulnerabilities can be mitigated by following the instructions
   listed in the Securing Your Web Browser document.
