On Tuesday, October 11, 2011, Microsoft is planning to release eight (8) Security Bulletins, addressing 23 vulnerabilities. Two of the bulletins are rated Critical and six are rated Important, addressing vulnerabilities in Internet Explorer, .NET Framework & Silverlight, Microsoft Windows, Microsoft Forefront UAG, and Microsoft Host Integration Server.
The bulletins address Remote Code Execution, Elevation of Privilege and Denial of Service, several requiring a restart. Whether required or not, it is advised to restart your computer after installing updates. In addition, due to issues many people experience when installing .NET Framework updates, it is advised that update be installed separately.
