Microsoft if fearing a new attack using a vulnerability in DirectX, a backbone system that allows multimedia in most MS applications.
The danger comes, says Microsoft, in a component of DirectX that relies on a library file called quartz.dll, which is used by a number of applications — including Internet Explorer — to play midi files. A specially designed midi file could cause a buffer overflow error and either pass control of the system to an attacker, cause damage to the system or use the system to set off another MSBlast-type attack.

Recent attacks have focused on exploiting vulnerabilities aknowledged by Microsoft.
