checksec not working under Python3

[hugsy]

Thanks for the bug report.
I think it's OK now, can you try and let me know ?

Thanks! Yea, that seemed to solve that problem.

I noticed now that gef doesnt show the same output as checksec.sh though:

gef> checksec
[+] checksec for '/bin/ls'
Canary: No
NX Support: Yes
PIE Support: Yes
RPATH: No
RUNPATH: No
Partial RelRO: No
Full RelRO: No

root@xxx# ~/checksec.sh --file /bin/ls
RELRO STACK CANARY NX PIE RPATH RUNPATH FILE
Partial RELRO Canary found NX enabled No PIE No RPATH No RUNPATH /bin/ls

I think the checksec.sh output is the correct one, but I'd have to do some more testing to confirm.

That's pretty weird, I get the same results (gef & checksec.sh identical output) on the Ubuntu VM (with Python3) Can you provide more details so I can try to reproduce ?

[truemongo]

Same environment here, Ubuntu with GDB+Python3.
Looking at the source I think the problem is the following, in do_check() method:

    ret = subprocess.check_output( cmd )
    ret = str( buf )

The 2nd line should probably be ret = str( ret ). That seems to fix the problem.

Fixed now. Thanks again for reporting !
