Microsoft Security Bulletin MS08-052

Vulnerabilities in GDI+ Could Allow Remote Code Execution (954593)

Severity: Critical
Vulnerabilities:

• GDI+ VML Buffer Overrun Vulnerability - CVE-2007-5348
  A remote code execution vulnerability exists in the way that GDI+ handles gradient sizes. The vulnerability could allow remote code execution if a user browses to a Web site that contains specially crafted content. 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 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.
• GDI+ EMF Memory Corruption Vulnerability - CVE-2008-3012
  A remote code execution vulnerability exists in the way that GDI+ handles memory allocation. The vulnerability could allow remote code execution if a user opens a specially crafted EMF image file or browses to a Web site that contains specially crafted content. 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 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.
• GDI+ GIF Parsing Vulnerability - CVE-2008-3013
  A remote code execution vulnerability exists in the way that GDI+ parses GIF images. The vulnerability could allow remote code execution if a user opens a specially crafted GIF image file or browses to a Web site that contains specially crafted content. 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 data; or create new accounts.
• GDI+ WMF Buffer Overrun Vulnerability - CVE-2008-3014
  A remote code execution vulnerability exists in the way that GDI+ allocates memory for WMF image files. The vulnerability could allow remote code execution if a user opens a specially crafted WMF image file or browses to a Web site that contains specially crafted content. 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 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.
• GDI+ BMP Integer Overflow Vulnerability - CVE-2008-3015
  A remote code execution vulnerability exists in the way that GDI+ handles integer calculations. The vulnerability could allow remote code execution if a user opens a specially crafted BMP image file. 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 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.

Microsoft Security Bulletin MS08-053

Vulnerability in Windows Media Encoder 9 Could Allow Remote Code Execution (954156)

Vulnerabilities:

• Windows Media Encoder Buffer Overrun Vulnerability - CVE-2008-3008
  A remote code execution vulnerability exists in the WMEX.DLL ActiveX control installed by Windows Media Encoder 9 Series. The vulnerability could allow remote code execution if a user views a specially crafted Web page. If a user is logged on with administrative user rights, 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 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.

Microsoft Security Bulletin MS08-054

Vulnerability in Windows Media Player Could Allow Remote Code Execution (954154)

Severity: Critical
Vulnerabilities:

• Windows Media Player Sampling Rate Vulnerability - CVE-2008-2253
  A remote code execution vulnerability exists in Windows Media Player 11. An attacker could exploit the vulnerability by constructing a specially crafted audio file that could allow remote code execution when streamed from a Windows Media server using Windows Media Player 11. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Microsoft Security Bulletin MS08-055

Vulnerability in Microsoft Office Could Allow Remote Code Execution (955047)

Severity: Critical
Vulnerabilities:

• Uniform Resource Locator Validation Error Vulnerability - CVE-2008-3007
  A remote code execution vulnerability exists in the way that Microsoft Office handles specially crafted URLs using the OneNote protocol handler (onenote://). The vulnerability could allow remote code execution if a user clicks a specially crafted OneNote URL. 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 data; or create new accounts with full user rights.
