                 Technical Cyber Security Alert TA05-165A
         Microsoft Windows and Internet Explorer Vulnerabilities

       Original release date: June 14, 2005
       Last revised: --
       Source: US-CERT

    Systems Affected

         * Microsoft Windows
         * Microsoft Internet Explorer

       For more complete information, refer to the Microsoft Security
       Bulletin Summary for June, 2005.


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

    I. Description

       Microsoft Security Bulletins for June, 2005 address a number of
       vulnerabilities in Windows, Internet Explorer, Outlook Express,
       Outlook Web Access, ISA Server, the Step-by-Step Interactive Training
       engine, and telnet. Further information about the more serious
       vulnerabilities is available in the following Vulnerability Notes:

       VU#189754 - Microsoft Internet Explorer buffer overflow in PNG image
       rendering component

       A buffer overflow in the PNG image rendering component of Microsoft
       Internet Explorer may allow a remote attacker to execute code on a
       vulnerable system.

       VU#489397 - Microsoft Server Message Block vulnerable to buffer

       Microsoft Server Message Block (SMB) is vulnerable to a buffer
       handling flaw when processing incoming SMB packets that may lead to
       remote code execution.

       VU#851869 - Microsoft HTML Help input validation error

       Microsoft HTML Help fails to properly validate input data, allowing a
       remote attacker to execute arbitrary code.

    II. Impact

       Exploitation of the most serious of these vulnerabilities could allow
       a remote, unauthenticated attacker to execute arbitrary code with
       SYSTEM privileges. This would allow an attacker to take complete
       control of a vulnerable system. An attacker could also execute
       arbitrary code with user privileges, or cause a denial of service.

    III. Solution

    Apply updates

       Microsoft has provided the patches for these vulnerabilities in the
       Security Bulletins and on Windows Update.


       Please see the individual vulnerability notes for workarounds.
