Comments: The update refers to Outlook Express, though it is Windows Mail that gets patched in Vista. Though not specifically for the core of Vista, all Vista releases include Windows Mail, so it is relevant. The update resolves two privately reported and two publicly disclosed vulnerabilities. Maximum rating is ‘Critical’, but is only listed as ‘Important’ on my machine.
