Microsoft fix 23 vulnerabilities for "Patch Tuesday"

Microsoft have released their "Patch Tuesday" update for October 11th which includes a critical flaw that could give attackers the ability to remotely spread a virus through compromised Internet Explorer and Windows users. The security update will contain eight security bulletins for a total of 23 bugs.

The other critical vulnerability Microsoft will fix exists in the company's .NET and Silverlight frameworks. The remaining six bulletins address flaws in Windows, Forefront Unified Access Gateway and Host Integration Server, and are all listed as "important," meaning their exploitation could result in the compromise of user data. Software affected by these vulnerabilities includes Internet Explorer versions 6 through 8, Windows 7, Windows XP, Windows Server 2003 and 2008 and Windows Vista.
