Microsoft's Windows 7 Bug Fixed With Security Update

In its security bulletin, released Tuesday, Microsoft stated that the critical fix was for just about every version of Windows, including Windows 2000, XP, Vista, Server 2003 and Server 2008. However, the software giant failed to mention that the update also was intended for Windows 7 under its "Affected Software" heading.

Microsoft did, however, mention that the update affected Windows 7 under the "Frequently Asked Questions" section. In addition to Windows 7, the patch repaired critical flaws in Windows Server 2008 Service Pack 2 Beta and Windows Vista Service Pack 2 Beta.

Altogether, the patch bundle resolved a total of four image vulnerabilities in the Windows kernel, the most serious of which could allow hackers to install malicious code on users' computers without any user intervention by enticing a victim to view a maliciously crafted EMF or WMF image file. The user could then download a Trojan or other piece of malware that would enable hackers to take complete control of the machine and steal sensitive data. Other vulnerabilities repaired by the update could leave the user susceptible to a denial of service attack.
