The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2 does not properly validate the user-mode input associated with the editing of an unspecified desktop parameter, which allows local users to gain privileges via a crafted application, aka "Windows Desktop Parameter Edit Vulnerability."
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
