Yesterday, Microsoft have released a patch for 55 distinct security vulnerabilities in its Windows operating system and other software. In the bundle of 9 updates, three patch fix the security bug on windows operating system, that Microsoft considers 'Critical'. These three security updates was marked as critical because it can be exploit remotely with no or little users interaction .
Other bulk of 41 updates is addressed for Internet Explorer. This one is much important for all the organisation and business houses which rely on the Internet Explorer. Other left security updates is itself applied for Windows and some are for various version of Microsoft office. You can check the list of the updates that were released yesterday.
The architecture to properly support the fix provided in the update does not exist on Windows Server 2003 systems, making it infeasible to build the fix for Windows Server 2003. To do so would require re-architecting a very significant amount of the Windows Server 2003 operating system, not just the affected component. The product of such a re-architecture effort would be sufficiently incompatible with Windows Server 2003 that there would be no assurance that applications designed to run on Windows Server 2003 would continue to operate on the updated system.Among all these patches one critical patches is fix for the vulnerability in Microsoft Group Policy that could present unique threats for enterprises that rely on Active Directory, the default authentication mechanism on corporate Windows networks. The vulnerability is remotely exploitable and can be used to grant attackers administrator-level privileges on the targeted machine or device – that means 10s of millions of PCS, and other devices, if left untreated.
There are many patches so users applying these updates have to restart system many times. All these updates are also available via Windows Update, so users can also updates the patches from it.
