Microsoft Internet Explorer Channel Definition Format code execution

ie-cdf-execute-code (19137)

Medium Risk

Description:

Microsoft Internet Explorer running on Windows 2000, Windows XP, Windows Server 2003, Windows 98, Windows 98 SE, and Windows ME could allow a remote attacker to obtain sensitive information or execute arbitrary code. The Channel Definition Format (CDF) is used to store files that organize related Web documents into a hierarchical structure. Certain URLs found in CDF files are not properly validated by Internet Explorer. A remote attacker could create a specially-crafted URL link, which would be executed in the victim's Web browser within the security context of the Internet zone, once the link is clicked. An attacker could exploit this vulnerability by creating a malicious Web page and hosting it on a Web site or by sending it to a victim as an HTML email.

Platforms Affected:

• Microsoft, Windows 2000 SP4
• Microsoft, Windows 2000 SP3
• Microsoft, Windows 2003 Server
• Microsoft, Windows 2003 Server Itanium
