pefile.write() doesn't correctly write out Section Charistic Flags #19

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When changing the flags in pefile.SectionStructures structure 
(IMAGE_SCN_MEM_WRITE in my case) the information isn't written to the file.

Reproduce:
load exe
change IMAGE_SCN_MEM_WRITE flag in .text section (tho it shouldn't matter)
write file to disk
check flags -> same as before

Beware that the characteristics of the section are stored in the 
"Characteristics" attribute of the section instance. Modifying that attribute 
will lead to successful modification of the value in the saved image.
In the other hand, if you are merely changing "section.IMAGE_SCN_MEM_WRITE" 
from True to False or viceversa, that will have no effect as those attributes 
are there simply to make the flags more easily accessible/readable.
