Technical Cyber Security Alert TA05-221A
Microsoft Windows and Internet Explorer Vulnerabilities
Original release date: August 09, 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 August, 2005.
Overview
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 on an affected
system.
I. Description
Microsoft Security Bulletins for August, 2005 address vulnerabilities
in Windows and Internet Explorer. Further information is available in
the following Vulnerability Notes:
VU#965206 - Microsoft Internet Explorer JPEG rendering library
vulnerable to buffer overflow
Microsoft Internet Explorer contains a flaw related to JPEG image
rendering that may allow an attacker to remotely execute arbitrary
code.
(CAN-2005-1988)
VU#959049 - Several COM objects cause memory corruption in Internet
Explorer
Microsoft Internet Explorer allows instantiation of non-ActiveX COM
objects, which may allow an attacker to execute arbitrary code or
crash Internet Explorer.
(CAN-2005-1990)
VU#998653 - Microsoft Plug and Play contains a buffer overflow
vulnerability
Microsoft Plug and Play contains a flaw in the handling of message
buffers that may result in a local or remote denial-of-service
condition and arbitrary code execution.
(CAN-2005-1983)
VU#490628 - Microsoft Remote Desktop Protocol service contains an
unspecified vulnerability
An input validation error in the Microsoft Remote Desktop Protocol
(RDP) service may allow a remote attacker to cause a denial-of-service
condition.
(CAN-2005-1218)
VU#220821 - Microsoft Print Spooler service contains a buffer overflow
A buffer overflow in the Microsoft Print Spooler service may allow a
remote attacker to execute arbitrary code on a vulnerable system.
(CAN-2005-1984)
II. Impact
Exploitation of these vulnerabilities may allow a remote,
unauthenticated attacker to execute arbitrary code with SYSTEM
privileges or 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 the updates for these vulnerabilities in the
Security Bulletins and on the Microsoft Update site.
Workarounds
Please see the individual Vulnerability Notes for workarounds.
