use follow in dump or use ctrl+g and type the address and go there and look if yes does the length match to the word ptr in that is it 0x59 bytes long string ??? Quote:
but i think olly originally pushes dword (ill check it later) and it fetches the length from an earlier ReadMemory() or ReadCommand() or Find Ref() code so also could you please assemble the code i posted above and check it too the first param length is 0x 19 and the second param length is 0x 5b in my code also if youare pushing word then i would suggest you to do an equivalent to this in windows for i in `seq 1 65540`; echo -n A >> test.txt (this in bash would create a file test.txt containing AAAAAAAAAAAAAAAA 65540 times i dont know if windows echo supports it i think you have to write a bat file with for and execute it to make this dummy file ![]() and then use the bintodb.exe in the masm package and use it to assemble the code put those dbs here vulnstring db "65,65,65,65,65,65 db "65,65,65, for 65540 times so that the length crosses the word barrier so that we can deduce if such a long string will still work or not as it is expected to work or still crashes on other bugs or overflows any way if you say the patch works fine with your modification on all targets it think it is still fine some thing is better than nothing ![]() thanks once again |
