Microsoft Office Publisher

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:
