Microsoft on Thursday said it will provide a fix next week for zero-day flaws in Microsoft Server Message Block and Internet Information Services that could allow an attacker to take control of a computer.

Those are just two of the 34 vulnerabilities addressed in 13 bulletins (eight of which are critical and five of which are rated important) that will be fixed during Patch Tuesday, according to a blog post on the announcement. The bulletins affect Windows, Internet Explorer, Office, Silverlight, Forefront, Developer Tools and SQL Server, the advisory shows.

The Server Message Block (SMB) flaw was reported a month ago. At the time, Microsoft said it affected Vista, Windows Server 2008, and the "release candidate" version of Windows 7, but not the final version that was completed in July. Windows Server 2008 R2 is not vulnerable, and neither are the earlier Windows XP and Windows 2000 operating systems .

Microsoft, which previously released a temporary fix for the SMB hole, reported the Internet Information Services (IIS) flaw in the File Transfer Protocol in August. Its advisory says there have been limited attacks that use the IIS flaw exploit code, which was posted on the Milw0rm website, according to IDG News Service.

Talkback

Bulletin 5 presents an increased threat for drive-by malware because it concerns the most current versions of IE - versions 7 and 8 - on multiple operating system platforms making this vulnerability a prime target for web-born malware writers and malicious web operators.

Of the batch, Bulletin 12, raises a red flag. Labelled as critical, it affects a large number of operating systems, core services and applications. Given its prevalence, it is most likely a low level vulnerability shared within the operating system itself that needs to be fixed. If exploited, it could allow the propagation of an Internet worm without user action. Before deploying this patch into production environments, it is essential that IT administrators test it vigorously to ensure services are not impacted by unexpected results.

Organisations should also pay close attention to the details listed in Bulletins 7 and 9, two important vulnerabilities, to determine how critical they are within their business environments. Vulnerabilities involving spoofing and elevation of privilege should raise an alarm for IT administrators as they can potentially have a big impact on their ability to verify trusted destinations and control user privileges within their organisations – two conceptual things that IT never wants to lose control over.

In addition to these four bulletins, all of the critical vulnerabilities are labelled as remote code execution, which require a restart and are across a broad variety of Windows platforms and applications.
