A vulnerability in the Microsoft Windows TrueType font parsing component could allow an attacker to cause a denial-of-service condition in Microsoft Windows.
The Microsoft Windows kernel includes a driver (win32k.sys) that handles a variety of graphics processing tasks, including the processing of TrueType fonts. A vulnerability exists in the way this driver validates array indexes. This can cause Windows to crash with a "blue screen."
By convincing a user to open a specially-crafted TrueType font file, a remote, unauthenticated attacker could cause a denial-of-service condition.
