Google maintains a Product Security Response Team that prioritizes bug reports and coordinates their handling across relevant engineering groups. Quite a few security companies and organizations produce vulnerability databases, cataloguing bugs and reporting trends across the industry based on the data they compile. Unfortunately, the data behind these reports is commonly inaccurate or outdated to some degree. The truth is that maintaining an accurate and reliable database of this type of information is a significant challenge.
"We most recently saw this reality play out last week after the appearance of IBM X-Force 2010 Mid-Year Trend and Risk Report. We questioned a number of surprising findings concerning Google's vulnerability rate and response record, and after discussions with IBM, we discovered a number of errors that had important implications for the report's conclusions. IBM worked together with us and promptly issued a correction to address the inaccuracies," states Google.
