Qualys has released the following checks for these new vulnerabilities:

Microsoft Windows Bluetooth Stack Could Allow Remote Code Execution
SEVERITY: Critical  4
QUALYS ID: 42008
VENDOR REFERENCE: MS08-030, 951376
CVE REFERENCE: CVE-2008-1453
CVSS SCORES: Base 10/ Temporal 7.4
THREAT: Bluetooth is an industry standard protocol that enables wireless connectivity for computers, handheld devices, keyboards, mice, mobile phones and other devices. A remote code execution vulnerability exists in the Bluetooth stack because the Bluetooth stack does not correctly handle a large number of service description requests.
IMPACT: An attacker would rapidly send a large number of crafted Service Discovery Protocol (SDP) packets to an affected system. The vulnerable system would react to those packets and allow an attacker to run code with elevated privileges and take complete control.
SOLUTION: Refer to Microsoft Security Bulletin MS08-030 for further details on this vulnerability and patch instructions. Microsoft has rated this issue as Critical.

Cumulative Security Update for Internet Explorer
SEVERITY: Critical  4
QUALYS ID: 100058
VENDOR REFERENCE: MS08-031, 950759
CVE REFERENCE: CVE-2008-1442, CVE-2008-1544
CVSS SCORES: Base 8.3/ Temporal 6.5
THREAT: A remote code execution vulnerability exists in the way Internet Explorer displays a Web page that contains certain unexpected method calls to HTML objects. The issue occurs because of the way that it processes data streams.
IMPACT: An attacker could exploit the vulnerability by constructing a specially crafted Web page. An attacker who successfully exploited this vulnerability could also gain the same user rights as the logged-on user.
SOLUTION: Refer to Microsoft Security Bulletin MS08-031 for further details on this vulnerability, including a list of affected and non-affected software. Microsoft has rated this issue as Critical.

Cumulative Security Update of ActiveX Kill Bits
SEVERITY: Critical  4
QUALYS ID: 90441
VENDOR REFERENCE: MS08-032, 950760
CVE REFERENCE: CVE-2007-0675
CVSS SCORES: Base 6.8/ Temporal 5
THREAT: This security update resolves a publicly reported vulnerability for the Microsoft Speech API.
IMPACT: The vulnerability could allow remote code execution if a user viewed a specially crafted Web page using Internet Explorer and has the Speech Recognition feature in Windows enabled. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. This update also includes a kill bit for software produced by BackWeb.
SOLUTION: Refer to Microsoft Security Bulletin MS08-032 for further details on this vulnerability, including a list of affected and non-affected software. Microsoft has rated this issue as Moderate.

Vulnerabilities in DirectX Could Allow Remote Code Execution
SEVERITY: Critical  4
QUALYS ID: 90438
VENDOR REFERENCE: MS08-033, 951698
CVE REFERENCE: CVE-2008-0011,CVE-2008-1444
CVSS SCORES: Base 7.5/ Temporal 5.9
THREAT: This is a critical security update which affects all supported editions of Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008. This security update resolves two privately reported vulnerabilities in Microsoft DirectX that could allow remote code execution if a user opens a specially crafted media file.
IMPACT: An attacker who successfully exploited either of these vulnerabilities could install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
SOLUTION: The security update addresses the vulnerability by modifying the way that DirectX handles MJPEG and SAMI format files. Refer to Microsoft Security Bulletin MS08-033 for further details on this vulnerability and patch instructions. Microsoft has rated this issue as Critical.

Vulnerability in WINS Could Allow Elevation of Privilege
SEVERITY: Critical  4
QUALYS ID: 90439
VENDOR REFERENCE: MS08-034, 948745
CVE REFERENCE: CVE-2008-1451
CVSS SCORES: Base 6.9/ Temporal 5.1
THREAT: An elevation of privilege vulnerability exists in the Windows Internet Name Service (WINS) in the way that WINS does not sufficiently validate the data structures within specially crafted WINS network packets.
IMPACT: Successful exploitation could allow a local attacker to run code with elevated privileges. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete date; or create new accounts.
SOLUTION: Refer to Microsoft Security Bulletin MS08-034 for further details on this vulnerability and patch instructions. Microsoft has rated this issue as Important.

Vulnerability in Active Directory Could Allow Denial of Service
SEVERITY: Serious  3
QUALYS ID: 90443
VENDOR REFERENCE: MS08-035, 953235
CVE REFERENCE: CVE-2008-1445
CVSS SCORES: Base 5.4/ Temporal 4
THREAT: A denial of service vulnerability exists in implementations of Active Directory on several Windows operating systems. It also exists in implementations of Active Directory Application Mode (ADAM). The vulnerability is due to insufficient validation of specially crafted LDAP requests.
IMPACT: An attacker who successfully exploited this vulnerability could cause the computer to stop responding and automatically restart.
SOLUTION: Refer to Microsoft Security Bulletin MS08-035 for further information and patch instructions. Microsoft has rated this issue as Important.

Vulnerabilities in Pragmatic General Multicast (PGM) Could Allow Denial of Service
SEVERITY: Serious  3
QUALYS ID: 90442
VENDOR REFERENCE: MS08-036, 950762
CVE REFERENCE: CVE-2008-1440, CVE-2008-1441
CVSS SCORES: Base 5.4/ Temporal 4
THREAT: These vulnerabilities exist in implementations of the Pragmatic General Multicast protocol on several Windows Operating systems. The vulnerability is due to improper validation of specially crafted PGM packets. Also the protocols parsing code does not properly validate specially crafted PGM fragments and will cause the affected system to become non responsive until the attack has ceased.
IMPACT: An attacker who successfully exploited this vulnerability could cause the computer to become non responsive and require a restart to restore functionality.
SOLUTION: Microsoft released security bulletin MS08-036 to address this vulnerability. Microsoft has rated this issue as Important.
