FIXING THE .LNK/.INK VIRUS IN VISTA / WINDOWS 7
The first most common windows shell vulnerability I have found in the latest Microsoft Windows releases is Ink/Lnk icon association, which make common icons and programs into some unknown program .Ink/Lnk.
First, some information as released by Microsoft.
The vulnerability exists because Windows incorrectly parses shortcuts in such a way that malicious code may be executed when the icon of a specially crafted shortcut is displayed. This vulnerability can be exploited locally through a malicious USB drive, or remotely via network shares and WebDAV. An exploit can also be included in specific document types that support embedded shortcuts.
Here’s a description of the vulnerability
What causes this threat?
When attempting to load the icon of a shortcut, the Windows Shell does not correctly validate specific parameters of the shortcut.
In other words, a design flaw.
This vulnerability is present in 32-bit and 64-bit flavors of Windows XP, Server 2003, Vista, Server 2008, Windows 7 (including beta Service Pack 1) and Server 2008 R2 (including beta Service Pack 1).
Microsoft furthermore recommends to block the download of lnk and pif files, but does not go into detail on how to do that. Visit the updated security advisory for additional information.
