PEDA-Screen

PEDA - Python Exploit Development Assistance for GDB

---

Changes Made

A hacky screen extension for use with gdb-peda. Moves the inline disassambly, register and stack views into a seperate tmux seperated screen.

• Commands to use the screen extension:
  • scron -- turns on the the screen extension and moves the inline debugger info to a newly opened tmux seperated screen
  • scrclr -- clears the debugger info screen
  • scroff -- turns off the the screen extension and moves the inline debugger info back to the main screen

Issues

Requires the "remember window size option to be disabled in konsole, "settings -> configure konsole -> general" The screen extension is currently hardcoded for use with the konsole terminal emulator and requires the terminal that is running gdb-peda to be using /dev/pts/0 and have no other pts devices in use.

Todo

• add dynamic support for all terminal emulators
• remove dependancy on the terminal running gdb-peda to use /dev/pts/0
• remove requirment for only one terminal to be in use prior to screen extenions being run

Key Features:

• Enhance the display of gdb: colorize and display disassembly codes, registers, memory information during debugging.
• Add commands to support debugging and exploit development (for a full list of commands use peda help):
  • aslr -- Show/set ASLR setting of GDB
  • checksec -- Check for various security options of binary
  • dumpargs -- Display arguments passed to a function when stopped at a call instruction
  • dumprop -- Dump all ROP gadgets in specific memory range
  • elfheader -- Get headers information from debugged ELF file
  • elfsymbol -- Get non-debugging symbol information from an ELF file
  • lookup -- Search for all addresses/references to addresses which belong to a memory range
  • patch -- Patch memory start at an address with string/hexstring/int
  • pattern -- Generate, search, or write a cyclic pattern to memory
  • procinfo -- Display various info from /proc/pid/
  • pshow -- Show various PEDA options and other settings
  • pset -- Set various PEDA options and other settings
  • readelf -- Get headers information from an ELF file
  • ropgadget -- Get common ROP gadgets of binary or library
  • ropsearch -- Search for ROP gadgets in memory
  • searchmem|find -- Search for a pattern in memory; support regex search
  • shellcode -- Generate or download common shellcodes.
  • skeleton -- Generate python exploit code template
  • vmmap -- Get virtual mapping address ranges of section(s) in debugged process
  • xormem -- XOR a memory region with a key

Installation
