Breaking News

heaptrace is a heap debugger for monitoring glibc heap operations in ELF64 (x86_64) binaries. Its objective is to assist visualize heap operations when debugging binaries or doing heap pwn.

  • replaces addresses with easy-to-understand symbols
  • detects heap corruption and reminiscence leakage points
  • can debug in gdb at any level (--break)
  • helps all ELF64 (x86_64) binaries no matter ASLR or compiler settings (together with stripped binaries)

How are heaptrace and valgrind completely different?

Official Releases

See the .deb and .rpm launch information, and a pre-compiled binary on the Releases web page.

Ubuntu PPA

$ sudo add-apt-repository ppa:arinerron/heaptrace
$ sudo apt-get replace
$ sudo apt-get set up heaptrace

Arch Person Repository (PKGBUILD)

Use your most popular AUR helper to put in one of many two following packages:

$ trizen -S heaptrace-git
... OR ...
$ trizen -S heaptrace

Compile from Supply

$ git clone && cd heaptrace
$ make
$ sudo make set up
$ heaptrace ./goal

You possibly can specify arguments to heaptrace earlier than specifying the binary title:

heaptrace [options...] <goal> [args...]
heaptrace [options...] --attach <pid>

-p <pid>, --attach <pid>, --pid <pid>
Tells heaptrace to connect to the required pid
as a substitute of working the binary from the `goal`
argument. Observe that if you happen to specify this argument
you would not have to specify `goal`.

-b <expression>, --break=<expression>, --break-at=<expression>
Ship SIGSTOP to the method when the required
`expression` is glad and fasten the GNU debugger
(gdb) to the method.

This argument helps complicated expressions. Please
See the documentation for extra info:

-B <expression>, --break-after=<expression>
Just like `--break`. Replaces the tracer
course of with gdb, however solely af ter the heap operate
returns. See the documentation for extra info:

-e <title=worth>, --environ=<title=worth>, --environment=<title=worth>
Units a single environmental variable. Helpful for
setting runtime settings for the goal comparable to
LD_PRELOAD=./ with out having them have an effect on
heaptrace's runtime configuration. This selection can
be used a number of instances.

-s <sym_defs>, --symbols=<sym_defs>
Override the values heaptrace detects for the
malloc/calloc/free/realloc/reallocarray symbols.
Helpful if heaptrace fails to robotically
determine heap capabilities in a stripped binary. See
the wiki for more information.

-F, --follow-fork, --follow
Tells heaptrace to detach the mother or father and observe
the kid if the goal calls fork(), vfork(), or

The default conduct is to detach the kid and
solely hint the mother or father.

-G <path>, --gdb-path <path>
Tells heaptrace to make use of the trail to gdb specified
in `path` as a substitute of /usr/bin/gdb (default).

-w <width>, --width=<width>, --term-width=<width>
Power a sure terminal width.

-o <file>, --output=<file>
Write the heaptrace output to `file` as a substitute of
/dev/stderr (which is the default output path).

-v, --verbose
Prints verbose info comparable to line numbers in
supply code given the required debugging data is
saved within the ELF.

-V, --version
Shows the present heaptrace model.

-h, --help
Exhibits this assist menu.

  • For instance, if you happen to needed to robotically connect gdb at operation #3, you’d execute heaptrace --break=3 ./my-binary. Please see the wiki documentation for extra info on the way to use this argument.
  • See the wiki documentation for extra info on the way to use the -s/--symbol argument to debug stripped binaries that heaptrace did not robotically determine capabilities in.
  • Set the $NO_COLOR argument to take away ANSI coloration codes from output. This selection remains to be in growth and can be transformed into an argument quickly.

I am glad to assist if you happen to expertise a bug or have any suggestions. Please see the GitHub Points web page.
