\n Microsoft Windows and Internet Explorer Vulnerabilities<\/p>\n
Original release date: August 09, 2005
\n Last revised: —
\n Source: US-CERT<\/p>\n
Systems Affected<\/p>\n
* Microsoft Windows
\n * Microsoft Internet Explorer<\/p>\n
For more complete information, refer to the Microsoft Security
\n Bulletin Summary for August, 2005.<\/p>\n
Overview<\/p>\n
Microsoft has released updates that address critical vulnerabilities
\n in Windows and Internet Explorer. Exploitation of these
\n vulnerabilities could allow a remote, unauthenticated attacker to
\n execute arbitrary code or cause a denial of service on an affected
\n system.<\/p>\n
I. Description<\/p>\n
Microsoft Security Bulletins for August, 2005 address vulnerabilities
\n in Windows and Internet Explorer. Further information is available in
\n the following Vulnerability Notes:<\/p>\n
VU#965206 – Microsoft Internet Explorer JPEG rendering library
\n vulnerable to buffer overflow<\/p>\n
Microsoft Internet Explorer contains a flaw related to JPEG image
\n rendering that may allow an attacker to remotely execute arbitrary
\n code.
\n (CAN-2005-1988)<\/p>\n
VU#959049 – Several COM objects cause memory corruption in Internet
\n Explorer<\/p>\n
Microsoft Internet Explorer allows instantiation of non-ActiveX COM
\n objects, which may allow an attacker to execute arbitrary code or
\n crash Internet Explorer.
\n (CAN-2005-1990)<\/p>\n
VU#998653 – Microsoft Plug and Play contains a buffer overflow
\n vulnerability<\/p>\n
Microsoft Plug and Play contains a flaw in the handling of message
\n buffers that may result in a local or remote denial-of-service
\n condition and arbitrary code execution.
\n (CAN-2005-1983)<\/p>\n
VU#490628 – Microsoft Remote Desktop Protocol service contains an
\n unspecified vulnerability<\/p>\n
An input validation error in the Microsoft Remote Desktop Protocol
\n (RDP) service may allow a remote attacker to cause a denial-of-service
\n condition.
\n (CAN-2005-1218)<\/p>\n
VU#220821 – Microsoft Print Spooler service contains a buffer overflow<\/p>\n
A buffer overflow in the Microsoft Print Spooler service may allow a
\n remote attacker to execute arbitrary code on a vulnerable system.
\n (CAN-2005-1984)<\/p>\n
II. Impact<\/p>\n
Exploitation of these vulnerabilities may allow a remote,
\n unauthenticated attacker to execute arbitrary code with SYSTEM
\n privileges or with the privileges of the user. If the user is logged
\n on with administrative privileges, the attacker could take complete
\n control of an affected system. An attacker may also be able to cause a
\n denial of service.<\/p>\n
III. Solution<\/p>\n
Apply Updates<\/p>\n
Microsoft has provided the updates for these vulnerabilities in the
\n Security Bulletins and on the Microsoft Update site.<\/p>\n
Workarounds<\/p>\n
Please see the individual Vulnerability Notes for workarounds.<\/p>\n
