Introduction to urlmon.dll and IE8

The module urlmon.dll is a dynamic link library that contains functions used by Microsoft OLE (Object Linking and Embedding). The urlmon.dll program holds a uniform resource locator that allows client applications to access server resources on the Internet using a variety of protocols.

Windows Internet Explorer 8 was released on March 19, 2009. It is supported in Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista, Windows 7, and Windows Server 2008 on both 32-bit and 64-bit architectures. Security, ease of use, and improvements in RSS, CSS, and Ajax support are Microsoft's priorities for IE8.

Microsoft Internet Explorer is vulnerable to a buffer overflow in the URLMON.DLL library, which fails to properly check parameters returned from a Web site. By creating a malicious Web page and convincing an Internet Explorer client to visit the page, a remote attacker could overflow a buffer and cause the system to crash or execute arbitrary code on the system with the same privileges of the victim, once the Web page is visited. You cannot open a new Internet Explorer window or nothing occurs after you click a link.

Apply the appropriate patch for your system, as listed in the latest Microsoft Security Bulletin.
