Detailed Description |
| Business Impact: |
This vulnerability allows an attacker to obtain complete control over the target system and could be exploited through a malicious web page or email. IBM X-Force considers this to be one of the most severe vulnerabilities in this month’s Microsoft patch bundle because it could be used in an email worm. IBM X-Force advises users to disable VML in their browsers. VML is rarely used on the web and several exploits have targeted it over the past 12 months. CVE-2006-5745 is one such vulnerability, which IBM X-Force researchers discovered being exploited in the wild. |
