On October 13th, 2009, Microsoft started serving to Windows users patches for no less than 34 vulnerabilities, releasing the most security bulletins in the company’s history. The 13 security bulletins made available are designed to offer fixes for a range of security issues affecting Windows, Internet Explorer, Silverlight, Microsoft Office, Developer Tools, Forefront and SQL Server. Microsoft underlined that, despite the large number of patches, all security updates had been thoroughly tested, and only received the green light for broad release once they met specific quality standards.
Out of the total 13 security bulletins released, eight have received Microsoft’s maximum severity rating, namely Critical, indicating that they are designed to patch severe vulnerabilities that could allow for remote code execution in the eventuality of a successful attack. The remaining six patch packages have all been deemed Important, a less severe rating. However, customers should apply the patches offered by the Redmond company immediately. The simplest way to access the security updates is through Windows Update. Users with Automatic Updates enabled will have all patches automatically downloaded to their machines.
Microsoft revealed that no less than seven security bulletins with a maximum severity rating of Critical out of the total eight also had an exploitability index of 1. The highest possible exploitability index: 1 is indicative of the fact that Microsoft considers the possibility of exploit code becoming available in the wild for the seven flaws extremely likely, perhaps even within the first 30 days since the patches were released. This just in case you needed additional incentive to deploy the security updates. More »
