\nVulnerabilities<\/p>\n
Original release date: February 14, 2006
\n Last revised: —
\n Source: US-CERT<\/p>\n
Systems Affected<\/p>\n
* Microsoft Windows
\n * Microsoft Windows Media Player
\n * Microsoft Internet Explorer<\/p>\n
For more complete information, refer to the Microsoft Security
\n Bulletin Summary for February 2006.<\/p>\n
Overview<\/p>\n
Microsoft has released updates that address critical vulnerabilities
\n in Windows, Windows Media Player, and Internet Explorer. Exploitation
\n of these vulnerabilities could allow a remote, unauthenticated
\n attacker to execute arbitrary code or cause a denial of service on a
\n vulnerable system.<\/p>\n
I. Description<\/p>\n
Microsoft Security Bulletins for February 2006 address vulnerabilities
\n in Microsoft Windows, Windows Media Player, and Internet Explorer.
\n Further information is available in the following US-CERT
\n Vulnerability Notes:<\/p>\n
VU#312956 – Microsoft WMF memory corruption vulnerability<\/p>\n
Microsoft applications fail to properly handle WMF (Windows Meta File)
\n images, potentially allowing a remote attacker to execute arbitrary
\n code on a vulnerable system.
\n (CVE-2006-0020)<\/p>\n
VU#291396 – Microsoft Windows Media Player vulnerable to buffer
\n overflow in bitmap processing routine<\/p>\n
Microsoft Windows Media Player contains a buffer overflow
\n vulnerability that may allow a remote, unauthenticated attacker to
\n execute arbitrary code on a vulnerable system.
\n (CVE-2006-0006)<\/p>\n
VU#692060 – Microsoft Windows Media Player plug-in buffer overflow<\/p>\n
The Microsoft Windows Media Player plug-in for browsers other than
\n Internet Explorer contains a buffer overflow, which may allow a remote
\n attacker to execute arbitrary code.
\n (CVE-2006-005)<\/p>\n
VU#839284 – Microsoft Windows TCP\/IP fails to properly validate IGMP
\n packets<\/p>\n
Microsoft Windows implementations of the TCP\/IP protocol fail to
\n properly validate IGMP (Internet Group Management Protocol) packets,
\n leading to a denial-of-service condition.
\n (CVE-2006-0021)<\/p>\n
II. Impact<\/p>\n
Exploitation of these vulnerabilities may allow a remote,
\n unauthenticated attacker to execute arbitrary code with the privileges
\n of the user. If the user is logged on with administrative privileges,
\n the attacker could take complete control of an affected system. An
\n attacker may also be able to cause a 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 following US-CERT Vulnerability Notes for workarounds.<\/p>\n
