Ucspi-tcp Automated Code Checks

Development
#1

Patrick because you are well known in the TAILS community and so its likely they’ll listen, is it ok if you post to them my idea about scanning ucspi-tcp with Valgrind to check it doesn’t have memory safety issues? If anyone of them is familiar with C they may be able to patch it if problems arise. For static analysis of the code they can run it free through Coverity Scan or use PeachFuzzer.

I saw your comment on the Apparmor wishlist for a profile for this component, so we are ok in that front containment front, but its better not to have exploitable holes in the first place.

This may see unreasonable, but considering what we are potenitally up against, these measures are needed to cut it.

#2

Actually I am not sure what language ucspi-tcp is written in. I was looking at someone’s repo that had a Ruby wrapper for this package and mistaked it for the server itself.

#3

Reasonable. Sure, fixing holes in the first place is better. A multi layered security concept with AppArmor as one line of defense.

If problems are found, those can be reported against Debian. We’re lucky, that they have a dedicated security team, capable of C, and they would fix any security issues, and Whonix would automatically profit from their fixes in the security repository. Great to be based on Debian.

ucspi-tcp is written in C. For a quick look, you can use “apt-get source ucspi-tcp”.

I do not follow what Tails has to do with this? They are not using control-port-filter / ucspi-tcp.

#4

I assume TAILS uses it because that security enhancement for ControlPort Filter was discussed and implemented by them first.

https://www.whonix.org/forum/index.php/topic,342.msg2433

If they have nothing to do with it then I would like to be of assistance in auditing/fuzzing this package with your assistance. Just walk me through how to:

  1. compile ucspi from source with the correct debugging hooks so Valgrind can use it:
    http://valgrind.org/docs/manual/quick-start.html
    I’ll be happy to send the logs as I would have no idea whats in them or how to fix it , but the Debian guys will.

  2. Import the source code that I got from Debian repos in to Git so I can sign onto Coverity and run a check.

  3. Check with PeachFuzzer by following this guide: http://www.flinkd.org/2011/07/fuzzing-with-peach-part-1/

#5

There is also a few people who can be found on search engines, who forked ucspi-tcp, who might be willing and able to help this cause.

It was about limiting the characters allowed to 128, which is good, but has no relation to ucspi-tcp.

Terrific!

Sounds good.

debian/control contains.

Maintainer: Gerrit Pape <pape@smarden.org> Vcs-Git: http://smarden.org/git/ucspi-tcp.git/

Getting it from git is better than apt-get source, but anyway. The Vcs-Git link is currently offline. Please tell Gerrit Pape about it.

If there is no reply, we need to open a bug against Debian. But let’s not expect the worst.

3. Check with PeachFuzzer by following this guide: http://www.flinkd.org/2011/07/fuzzing-with-peach-part-1/
Sounds good.
#6

Shot Gerrit a mail.

What I could probably do know is try with Valgrind with the running package. Lacking explicit debugging options in the source code may make looking at the log harder. At the moment I am concerned about getting an idea if there is any memory problems at all.

When running it some hours ago, I had run into issues and so I’ll describe them.

#7 

gives error:

command not found


What an I doing wrong here? The command syntax is wrong but I can't figure out how to do this.

(Perhaps helpful for this: https://www.whonix.org/wiki/Tor_Browser#Verify_New_Identity)

This doesn’t even work when just typing “ucspi-tcp” in the shell, because there is no such command “ucspi-tcp”. The command we’re using is “tcpserver”. But also just running “tcpserver” won’t do much, just show “tcpserver”'s help.

Inspired by /usr/bin/controlportfilt.

On Whonix-Gateway.

Stop control-port-filter, because we’ll start tcpserver manually.

Let’s first test if this is working without involving valgrind.

sudo -u debian-tor tcpserver \ -v \ -1 \ -l host \ -H \ 0 \ 9052 \ /bin/bash -x -c /usr/lib/cpf-tcpserver

In Whonix 8, path is /usr/lib/whonix/cpf-tcpserver.

Check if Control Port Filter is still working (https://www.whonix.org/wiki/Tor_Browser#Verify_New_Identity).

Now involve valgrind into the equation.

sudo -u debian-tor valgrind --leak-check=yes tcpserver \ -v \ -1 \ -l host \ -H \ 0 \ 9052 \ /bin/bash -x -c /usr/lib/cpf-tcpserver

Maybe that helps.

valgrind --tool=memcheck --leak-check=full tcpserver

HEAP SUMMARY:
in use at exit: 0 bytes in 0 blocks
total heap usage: 0 bytes in 0 blocks

All heap blocks were freed – no leaks possible

Its my guess that the check needs to be run for every binary listed for this package?

#10
metapackage ucspi-tcp.

ucspi-tcp is not a metapackage by debian packaging definition. It’s just a package that provides multiple binaries. Not special in this regard.

Its my guess that the check needs to be run for every binary listed for this package?

You can do this, but I don’t think you’ll find anything interesting. Just as for example running “cp --help” doesn’t move any files, running “tcpserver” don’t use networking.

See my earlier answer https://www.whonix.org/forum/index.php/topic,381.msg2795.html#msg2795 on how to make a real world test and/or use tcpserver for any other real purpose. Once you found tcpserver useful, get valgrind involved.

#11

ok, but are these alternate parameters or all part of the same one?

-v \ -1 \ -l host \ -H \ 0 \ 9052 \ /bin/bash -x -c /usr/lib/cpf-tcpserver

#12

Not sure I understand. The parameters are copied from /usr/bin/controlportfilt. Those are really used there. Just have a look at /usr/bin/controlportfilt. Use them all at once. Otherwise for example “-v” alone will again do nothing.

#13

unknown user debian:tor

#14

debian-tor

Sorry.

#15

2 problems:

control-port-filter: unrecognized service

tcpserver: fatal: unable to bind: address already taken

I’d say the second error is the result of the first.

#16

controlportfiltd on Whonix 8. control-port-filter in Whonix 9.

(You can find the names of services/daemon check /etc/init.d/ folder and using bash competition [press after tying “sudo service c”].)

#17

/usr/lib/cpf-tcpserver no such file or directory
