A new release is here :). Thanks to all contributors for improving Pwndbg!
TL;DR what this release brings
- New commands or new flags:
attachp [pid | process name | device file]to attach to process by pid/name/device file,setflagto set CPU flags register values,telescope --reverse ...to see memory before a provided address,heap_configto set heap commands configuration,
- Better support for heap debugging without symbols:
- It is now possible to make Pwndbg determine the addresses of heap symbols when they are missing; also this is going to be improved further soon,
- If symbols cannot be found,
heap_configcan be used to configure symbols addresses, - We now define a
$heap_baseconvenient variable,
- better kernel debugging support - we use gdb-pt-dump to dump memory map information which should be much faster than the previous solution of parsing
monitor info meminformation, - better support for coredump debugging, mainly its vmmap display - we now parse what we can to get that info (btw GDB could improve on generating core dumps as well, see GDB-bugzilla#29508,
- we now display file paths based on
/proc/$pid/fd/$fdof opened files when showing the arguments of POSIX file APIs (open, read, write, close etc.) in the disasm view, - we now display tips when Pwndbg is launched (can be disabled with
set show-tips offadded do~/.gdbinit) - better support for virtualenvs - though, we display a warning that this may not work as expected (due to C libraries dependencies like libffi-dev etc)
- more tests and improved CI as we now test on Ubuntu 18.04, 20.04 and 22.04,
./tests.shnow has[<filter-tests-names>] [--pdb]arguments,
- ...and lots and lots of fixes!
