Top of section URL Parsing Cross-Domain Information Disclosure Vulnerability - CVE-2008-1448 An information disclosure vulnerability exists in Outlook Express and Windows Mail because the MHTML protocol handler incorrectly interprets MHTML URL redirections that could potentially bypass Internet Explorer domain restrictions when returning MHTML content. An attacker could exploit the vulnerability by constructing a specially crafted Web page. If the user viewed the Web page through Internet Explorer, the vulnerability could potentially allow information disclosure. An attacker who successfully exploited this vulnerability could read data from another Internet Explorer domain or the local computer. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2008-1448. Update Information Detection and Deployment Tools and Guidance Manage the software and security updates you need to deploy to the servers, desktop, and mobile systems in your organization.

For more information about SMS, visit the SMS Web site. For more detailed information, see Microsoft Knowledge Base Article 910723: Summary list of monthly detection and deployment guidance articles. Update Compatibility Evaluator and Application Compatibility Toolkit Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit 5.0. The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
