nmap v4.76 crashing when used with send-ip option

Sorry, we need more information about this bug as I wasn't able to reproduce the problem. What version of Ubuntu are you running? Are you running this sudo or as a real user? Can you run the command you list outside of the process and does it work? Thank you for more information!

oh sorry I thought I reported the bug in jaunty part.
So for the details, I am running an up to date 9.04

more /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=9.04
DISTRIB_CODENAME=jaunty
DISTRIB_DESCRIPTION="Ubuntu 9.04"

I already sent you the poc command, when I run it as root under bash i got the seg fault.

Could you, please, attach a backtrace (Instructions can be found here: https://wiki.ubuntu.com/Backtrace)? Let me know if need further assistance running the backtrace. Thank you for reporting this bug.

yeah, that's what I tried at the first time, but did not have the debugging symbols, hope it helps ...

Sorry, my fault. You need to install the version with debug symbols left in. Please, see this site on how to install it: https://wiki.ubuntu.com/DebuggingProgramCrash. Also, make sure to execute /usr/lib/debug/usr/bin/nmap rather than /usr/bin/nmap. The latter has the debug symbols and the former is the original stripped version. Thank you!

I can't find any nmap dbg or dbgsym package to install, please help.

Make sure you have the following in your /etc/apt/sources.list:

deb http://ddebs.ubuntu.com jaunty main restricted universe multiverse

Also, make sure the gpg key was successfully imported. Then you can:

sudo apt-get update

If you get errors at this point, please, double check the pgp key import. Once you update your apt cache you should be able to install it:

sudo apt-get install nmap-dbgsym=4.76-0ubuntu4

Thank you for your effort on this matter and thank you for submitting your bug report. Let me know if I can assist anymore. Thanks.

Jeff, thanks for your help. I was able to install the debug version. But I can't execute it !
See below:

#/usr/lib/debug/usr/bin/nmap
bash: /usr/lib/debug/usr/bin/nmap: cannot execute binary file

Any ideas ?

OK, lets try this. If you don't have strace installed, you can do the following:

sudo apt-get install strace

Then run:

sudo strace -Ff -tt nmap --send-ip -PE -sP -n 128.0.0.0/24 2>&1 | tee strace-nmap.log

If that works, post the log, please. Sorry this has become such a chore! Thank you for your continued effort to make Ubuntu better!

No problem, I did the strace for the 2 binaries, see enclosed.

Hopefully the strace output will be enough for the developers. Thank you for submitting this bug.
