I don't understand what you mean by "cave between sections". As I understand, the PE loader allocates a memory block for each section. However these blocks are disjoint and it seems memory areas between sections are undefined. Am I missing something ?

I redone the slides about PE, and included information about caves there:

Mod1.2PE refactoring and enhancement makes it much more readable. Good job.
S15 (section caves) is very clear for me.
So I suggest to rephrase in Mod1.3Shellcodes/S3
"cave between sections" --> "section caves"
