There were some very interesting vulnerabilities fixed this time and two of these were the PowerPoint Viewer 2003 vulnerabilities (CVE-2010-0033 and CVE-2010-0034). As such the vulnerabilities and analysis were simple and very straight-forward, however, an interesting case of how the "CExpParameterValidate::Read(..)" function in ole32.dll is implemented differently across versions of Windows has a big impact on the exploitability and even existence of the vulnerabilities.
