Qualys has released the following checks for these new vulnerabilities:

Microsoft Windows GDI+ Remote Code Execution Vulnerability
SEVERITY: Urgent  5
QUALYS ID: 90454
VENDOR REFERENCE: MS08-052, 954593
CVE REFERENCE: CVE-2007-5348, CVE-2008-3012, CVE-2008-3013, CVE-2008-3014, CVE-2008-3015
CVSS SCORES: Base 10/ Temporal 7.4
THREAT: A security issue exists in Microsoft Windows GDI+ which could allow remote code execution if a user views a specially-crafted image file using affected software or browses to a web site that contains specially-crafted content.
IMPACT: If a user is logged in with administrative user rights, an attacker who successfully exploits this vulnerability could take complete control of an affected system. An attacker could then 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: Refer to Microsoft Security Bulletin MS08-052 for more information on this issue. Microsoft has rated this issue as Critical.

Microsoft Windows Media Encoder 9 Remote Code Execution Vulnerability
SEVERITY: Critical  4
QUALYS ID: 115935
VENDOR REFERENCE: MS08-0553, 954156
CVE REFERENCE: CVE-2008-3008
CVSS SCORES: Base 8.3/ Temporal 6.5
THREAT: Windows Media Encoder is a media encoder which enables content developers to convert or capture both live and pre-recorded audio, video, and computer screen images to Windows Media formats. A remote code execution vulnerability exists in the WMEX.DLL ActiveX control installed by the Windows Media Encoder 9 Series.
IMPACT: If a user is logged in with administrative user rights, an attacker who successfully exploits this vulnerability could take complete control of an affected system.
SOLUTION: Refer to Microsoft Security Bulletin MS08-053 for further details on these vulnerabilities and patch instructions. Microsoft has rated this issue as Critical.

Microsoft Windows Media Player Remote Code Execution Vulnerability
SEVERITY: Critical  4

CVE REFERENCE: CVE-2008-3007
CVSS SCORES: Base 5.1/ Temporal 4
THREAT: A remote code execution vulnerability exists in Microsoft Office when a user clicks a specially-crafted OneNote URL.
IMPACT: An attacker who successfully exploits this vulnerability could take complete control of an affected system. An attacker could then 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: Refer to Microsoft Security Bulletin MS08-055 to address this issue. Microsoft has rated this issue as Critical.
