removePIE

This is an iOS tool which flips the MH_PIE bit in an application. This disables the Address Space Layout Randomization of an application.

Building

Building has been set-up to use OS-X, xCode and the iOS 6.0 SDK in default directories. execute "make" from the command line to execute the included makefile. This file includes the location of the iOS 6.0 SDK and the location of the ARM compiler of the SDK. The makefile also signs the compiled executable using the "codesign" tool provided by xCode. Alterations will need to be made to the makefile for compiling on Windows or Linux systems.

Usage

copy the compiled executable using scp i.e

desktop $ scp ./removePIE root@<IP address of phone>:/usr/bin/removePIE
root \# ./removePIE <application binary>

The is most likely located in a sub-directory of /private/var/mobile/Applications/ on the iphone

Issues

Issues have been found with applications on ios 5.1.1, i have found that you have to resign the application binary using the "codesign" tool in xcode to get it to execute. i have no idea as yet to why ldone or ldid doesn't work. ios 6.0.1 did not require re-signing of the application binary. '
