October 2009 Bulletin Release Advance Notification

Advance Notification for the October 2009 Security Bulletin Release

For October we are releasing 13 bulletins (eight critical and five important), addressing 34 vulnerabilities, affecting Windows, Internet Explorer, Office, Silverlight, Forefront, Developer Tools, and SQL Server. Most of these updates require a restart so please factor that into your deployment planning.

Among the updates this month, we are closing out two current security advisories:

· Vulnerabilities in SMB Could Allow Remote Code Execution (975497)

· Vulnerabilities in the FTP Service in Internet Information Services (975191)

Usually we do not go into this level of detail in the advance notification but we felt that it is important guidance so customers can plan accordingly and deploy these updates as soon as possible.

The target to release the October security updates is next Tuesday Oct. 13 at 10:00 a.m. PDT (UTC -8). Check back here at that time for a more detailed overview of the updates (including an overview video), our risk and impact summary and our deployment prioritization guide. More information about the upcoming security updates can be found here in the ANS.

Changes to Browser Capabilities in asp.net 4.0

ASP.NET determines the capabilities of the browser that a user is using to browse your site by using a feature called browser capabilities. Browser capabilities are represented by the HttpBrowserCapabilities object (exposed by the Request.Browser property). For example, you can use the HttpBrowserCapabilities object to determine whether the type and version of the current browser supports a particular version of JavaScript. Or, you can use the HttpBrowserCapabilities object to determine whether the request originated from a mobile device.

The HttpBrowserCapabilities object is driven by a set of browser definition files. These files contain information about the capabilities of particular browsers. In ASP.NET 4, these browser definition files have been updated to contain information about recently introduced browsers and devices such as Google Chrome, Research in Motion BlackBerry smartphones, and Apple iPhone.

The following list shows new browser definition files:

· blackberry.browser

· chrome.browser

· Default.browser

· firefox.browser

· gateway.browser

· generic.browser

· ie.browser

· iemobile.browser

· iphone.browser

· opera.browser

· safari.browser
