CVE REFERENCE: CVE-2006-0010
CVSS SCORES: Base: 5.6 / Temporal: 4.4
THREAT: A remote code execution vulnerability exists in Windows because of the way that it handles malformed embedded Web fonts. An attacker could exploit the vulnerability by constructing a malicious embedded Web font that could potentially allow remote code execution if a user visited a malicious Web site or viewed a specially crafted e-mail message.
IMPACT: An attacker who successfully exploited this vulnerability could take complete control of an affected system.
SOLUTION: Please refer the Microsoft Security Bulletin MS06-002 for more details and instructions on downloading and installing the patch. Microsoft has categorized this update as Critical.

Vulnerability in TNEF Decoding in Microsoft Outlook and Microsoft Exchange Could Allow Remote Code Execution (MS06-003)
SEVERITY: Critical  4
QUALYS ID: 90291
VENDOR REFERENCE: MS06-003 | 902412
CVE REFERENCE: CVE-2006-0002
CVSS SCORES: Base: 10 / Temporal: 7.4
THREAT: A remote code execution vulnerability exists in Microsoft Outlook and Microsoft Exchange Server because of the way that it decodes the Transport Neutral Encapsulation Format (TNEF) MIME attachment. An attacker could exploit the vulnerability by constructing a specially crafted TNEF message that could potentially allow remote code execution when a user opens or previews a malicious e-mail message or when the Microsoft Exchange Server Information Store processes the specially crafted message.
IMPACT: An attacker who successfully exploited this vulnerability could take complete control of an affected system.
SOLUTION: Microsoft has rated this vulnerability as critical and has released MS06-003 to address the issue. Please refer to the referenced advisory to obtain a list of patches for this issue. Microsoft has categorized this update as Important.
