Beschreibung:
Eine Sicherheitslücke wurde in Microsoft Windows gemeldet, die böswillige Personen ausnutzen können, um das System eines Benutzers zu kompromittieren.

Die Sicherheitslücke wird durch einen Integer-Unterlauf in der Implementierung der Vector Markup Language (VML) (vgx.dll) während der Verarbeitung von einer VML referenzierten Inhalten verursacht. Dies kann ausgenutzt werden, um einen Heap-basierten Pufferüberlauf zu verursachen, falls ein Benutzer z.B. eine bösartige Website mit dem Internet Explorer besucht.

Eine erfolgreiche Ausnutzung könnte die Ausführung von beliebigem Code erlauben.
