Vulnerability name/brief description	MS09-070 - Vulnerabilities in Active Directory Federation Services Could Allow Remote Code Execution (971726)
CVE/CAN name	CVE-2009-2508, CVE-2009-2509
Vendor threat level	Important

Solution	MS09-070
Vendor description	This security update resolves two privately reported vulnerabilities in Microsoft Windows. The more severe of these vulnerabilities could allow remote code execution if an attacker sent a specially crafted HTTP request to an ADFS-enabled Web server. An attacker would need to be an authenticated user in order to exploit either of these vulnerabilities.
SophosLabs comments	These vulnerabilities, although having the potential to allow arbitrary code execution, have not been publicly disclosed and require a relatively small attack window to exploit. SophosLabs advises users to apply this patch at their earliest convenience, but rate this issue as a medium level threat.
SophosLabs testing result	N/A
Currently known exploits	At the time of writing SophosLabs have not observed any malware attempting to exploit this vulnerability. Should this situation change samples will be analyzed and we will take action as necessary.
