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.

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)

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.

Solution

Apply Updates

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

Workarounds
