 * Microsoft Windows Media Player
 * Microsoft Internet Explorer

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

Overview

Microsoft has released updates that address critical vulnerabilities
in Windows, Windows Media Player, 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 Bulletins for February 2006 address vulnerabilities
in Microsoft Windows, Windows Media Player, and Internet Explorer.
Further information is available in the following US-CERT
Vulnerability Notes:

VU#312956 - Microsoft WMF memory corruption vulnerability

Microsoft applications fail to properly handle WMF (Windows Meta File)
images, potentially allowing a remote attacker to execute arbitrary
code on a vulnerable system.
(CVE-2006-0020)

VU#291396 - Microsoft Windows Media Player vulnerable to buffer
overflow in bitmap processing routine

Microsoft Windows Media Player contains a buffer overflow
vulnerability that may allow a remote, unauthenticated attacker to
execute arbitrary code on a vulnerable system.
(CVE-2006-0006)

VU#692060 - Microsoft Windows Media Player plug-in buffer overflow

The Microsoft Windows Media Player plug-in for browsers other than
Internet Explorer contains a buffer overflow, which may allow a remote
attacker to execute arbitrary code.
(CVE-2006-005)

VU#839284 - Microsoft Windows TCP/IP fails to properly validate IGMP
packets

Microsoft Windows implementations of the TCP/IP protocol fail to
properly validate IGMP (Internet Group Management Protocol) packets,
leading to a denial-of-service condition.
(CVE-2006-0021)

II. Impact

Exploitation of these vulnerabilities may allow a remote,
unauthenticated attacker to 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 the updates for these vulnerabilities in the
Security Bulletins and on the Microsoft Update site.

Workarounds

Please see the following US-CERT Vulnerability Notes for workarounds.
