DirectX consists of a set of low-level Application Programming Interfaces (APIs) used by Windows programs for multimedia support. Within DirectX, the DirectShow technology performs client-side audio and video sourcing, manipulation and rendering.

There are two buffer overruns with identical effects in the function used by DirectShow to check parameters in a Musical Instrument Digital Interface (MIDI) file. A security vulnerability results because it would be possible for a malicious user to attempt to exploit these flaws and execute code in the security context of the logged on user.
