# IntelliTamper (2.07/2.08) Language Catalog SEH Overflow Exploit.
    # we start off the exploitation with some fuzzing to determine how many bytes
    # before overwriting the pointer to next SEH
    # and pointer to SEH, we will try and overwrite each address with 41414141 "AAAA" [Pointer to next SEH]
    # and 42424242 "BBBB" [pointer to SEH].
   
# 0x41414141  Pointer to next SEH record
# 0x42424242  SE handler
#
# The vulnerability was discovered by 'Cnaph'. First click in "File" through your IntelliTamper and >> "Options"
# Then open your crafted file .CAT to update your Language catalog and your SEH will be overwritten.
# This exploit implements the SEH technique to exploit the issue . . .
# When doing SEH overwrites the pointer to the SEH handler is target to be overwritten,
# so we can gain control over the program.
#/Cnaph.
