Microsoft security expert on patching XP and Vista

Since shipping Vista six months ago, a Microsoft security expert says the company has patched 12 out of 27 disclosed vulnerabilities. This compares with XP's first six months, when Microsoft's security team patched 36 out of 39 known bugs. The data was published by Jeff Jones, a Microsoft security strategy director, who said that overall, Vista was doing better than XP. "Windows Vista continues to show a trend of fewer total and fewer high-severity vulnerabilities at the six month mark compared to its predecessor product, Windows XP," he wrote. He added that most of the unpatched Vista bugs were not critical.

Meanwhile, at the end of XP's first six months, there were two high-severity bugs that were unpatched. He published the data in an effort to show how Microsoft's software development methodology, called the Security Development Lifecycle (SDL) is yielding dividends.
