Microsoft Office Publisher

[jplopezy@xxxxxxxxx]

I found two ways to cause a denial of service on the Microsoft Office 
Publisher, this is done by creating a malformed file with the following 
characteristics: 

The first is to create a new file and modifying hexadicimal with an editor from 
the direction 00006B90 to 00006D90 with the letter "A", that causes the 
publisher fails, when you open with a debugger like ollydbg I strip the 
following exception 

Access violation when reading [00000046] 

Here I leave the proof of concept

The following causes the crash programme. We make a new file and adds an option 
to "wordart" inserting many letters "A", we open with a hex editor and change 
from the direction 000077D0 to 000079B0 with the letter "A". 

I leave the proof of concept:
