Microsoft Releases January 2007 Security Bulletin for Multiple Vulnerabilities
Summary
On January 9, 2007 Microsoft released their monthly security bulletin with the latest security updates for workstations and servers. The Microsoft bulletin lists four (4) security vulnerabilities, with three (3) listed as critical and one (1) listed as important. All these patches should be applied. The three critical ones are patches for Excel, Outlook ( not Outlook Express), and Internet Explorer's Vector Markup Language (VRML) component which all lead to remote execution when a system is left unpatched. The patch for the Microsoft Office 2003 Brazilian and Portuguese grammar checker vulnerability is designated as important. It is important that all patches with a critical designation be patched immediately, in particular the Outlook and IE VML patches since they affect a range of other components within the Windows operating system.The affected operating system platforms are:
* Windows Server 2003
* Windows XP
* Windows 2000 SP4
It is imperative patches with critical and important designations be applied due to the serious nature of remote execution vulnerabilities which can allow for complete compromise and control of systems originating from within campus and the Internet. Only the IE patch will be delivered via BigFix, as the other patches will require a local MS Office installation CD. Local Big Fix admins are to apply the MS Office patches manually. Details are in the Technical Details section of this post.
What to Do
Windows users can manually use "Windows Update" to download and install the current operating system patches. Additionally, it is recommended that all Windows machines have an automated patch management solution installed and configured on their system. Stanford provides BigFix to automatically patch Windows machines; it is available at http://patching.stanford.edu. A customized update will be delivered to workstations and servers via BigFix if you subscribed to this service. The BigFix deliverable includes only the IE VML patch (MS07-004) of this bulletin. Individual updates can be downloaded by going to the Summary section of this Microsoft website. Please remember to reboot your machine after patching manually, or when prompted to do so by Windows Update or by your BigFix administrator. Most patches do not take effect until after a reboot.
Technical Details
It is important all patches designated as critical or important be applied. The patches for the vulnerabilities are listed as follow, those with an * delivered via BigFix:
