Hi Alex/Daniel,

so THe IP of this SIP proxy is x.x.x.11 and I am using x.x.x.10 for the Mask
IP.

I see the coredump in the root of the server..

ls /core -lah
-rw------- 1 root root 134M 2010-11-20 19:48 /core

which is the date it crashed.

gdb /sbin/kamailio /core

This GDB was configured as "i486-linux-gnu"...
Cannot access memory at address 0xb75f3fb0


I am running gdb from debian repo on 5.04 maybe I need to compile gdb?

Thanks
Brian

Hello,

No, the problem is with the coredump AFAIK. Try looking thru 
/var/log/messages and dmesg for any indication of a coredump and the 
module that generated it. Please email those lines as well.

Hello
I see that the interesting line is already in the first mail . Please 
try this

readelf -S /path/to/topoh.so

You should have somethink like this

   [Nr] Name              Type            Addr     Off    Size   ES Flg 
Lk Inf Al
   [ 0]                   NULL            00000000 000000 000000 00      
0   0  0
.....
   [10] .init             PROGBITS        00001914 001914 000030 00  AX  
0   0  4
   [11] .plt              PROGBITS        00001944 001944 000430 04  AX  
0   0  4
   [12] .text             PROGBITS        00001d80 001d80 008008 00  AX  
0   0 16

Note the address of the .text segment (in my case is 0x00001d80)

Then

gdb /path/to/kamailio core.dump

in the gdb console load the topoh.so

add-symbol-file /path/to/topoh.so 0xb7004000 + 0x<offset of .text 
segment found as above>

then check the value of the Instruction pointer IP (0xb70070d9) Still in 
the gdb console

x/s 0xb70070d9

You will get an offset relative to a function where the crashed 
happened. This would be very helpful so please share the finding. Also 
do a info registers (in the gdb console) and paste the content of the 
registers as well.

Marius,

Only indications of core I have in any logs:

Nov 20 19:48:51 proxy sip[3381]: INFO: <core> [parser/msg_parser.c:339]:
ERROR: bad header field [CSeq: 1 REGISTER ACK]
Nov 20 19:48:54 proxy sip[3344]: ALERT: <core> [main.c:722]: child process

Nov 20 19:48:54 proxy sip[3344]: ALERT: <core> [main.c:725]: core was
generated
Nov 20 19:48:54 proxy sip[3344]: INFO: <core> [main.c:737]: INFO:

 Will respond to other mail now..

Brian

Hello

Did you give gdb the command
add-symbol-file /path/to/topoh.so 0xb7004000+0x00001d30

Gdb should inquire you if you want to lead topoh.so at offset 0xb7005d30 
(press 'y'). Then the IP should not be out of bounds ... it should be 
mapped to the topoh.so text segment. Ah, I have made a mistake, there 
should be no spaces between the address and the offset (as seen above)

Anyway you should get something like this (on my machine - on your use 
the offsets from above)
(gdb) add-symbol-file modules/topoh/topoh.so 0xb7004000+0x00001d80
add symbol table from file "modules/topoh/topoh.so" at
         .text_addr = 0xb7005d80
(y or n) y
Reading symbols from 
/home/marius/dev/sip-router/modules/topoh/topoh.so...done.

Then
(gdb) x/s 0xb70070d9
!!!!!!!!!!!!!!!!!!0xb70070d9 <th_get_hdr_cookie+25>: <Address 0xb70070d9 
out of bounds>!!!!!!!!!!!!!!!!!

The line between all the !!!!!! is the line I care about


Also don't forget
(gdb)info registers

Thank you
Marius

Hi Marius,

I hope this is what your after!

(gdb) add-symbol-file /lib/kamailio/modules/topoh.so 0xb7004000+0x00001d30
add symbol table from file "/lib/kamailio/modules/topoh.so" at
.text_addr = 0xb7005d30
(y or n) y
Reading symbols from /lib/kamailio/modules/topoh.so...done.

Yes I think it is

Looking at the debug messages I see the CSeq is wrong.

But :

int th_skip_msg(sip_msg_t *msg)
{
         if((get_cseq(msg)->method_id)&(METHOD_REGISTER|METHOD_PUBLISH))
                 return 1;

         return 0;
}

As the cseq is wrong the get_cseq macro probably returns a NULL Pointer 
who gets dereferenced (BANG the crash). Any other Ideas ?!

The patch is trivial ( if(!get_cseq(msg))) parse_cseq(....) ) something 
in this line. Daniel, What do you think ?

Marius

Are you able to test a patch if a provide one to you? I wanted to wait 
for Daniel's opinion as I have no way of testing it. If you have a dump 
of the attack traffic or you can generate more with bad CSEQ (as from 
the message log you provided) you can test the patch against your cfg 
and see if it still crashes(hope not). In my opinion the crash should be 
deterministic. You will find the trivial patch attached. If you can test 
it and it works I will push it to upstream (also to 3.0 branch). Keep in 
mind that other probles might appear as well during the processing of 
the SIP messages. If a core does appear please retry the steps in the 
previous mail with the new core and .so offset.

Apply the patch with the patch utility (copy to the modules/topoh and 
run patch < patch) . I await some feedback :)

The patch is ok, please go ahead and commit it.

Even if the cause for this case would be in some other place, the patch 
is still good and harmless for proper formatted sip messages.

Thanks,
Daniel

Hello,

Did this fix make it to the main 3.1 - I did install 3.1 last week and just
checked the source..

int th_skip_msg(sip_msg_t *msg)
{
        if (!get_cseq(msg)) {
                LM_WARN("Invalid/Unparsed CSeq in message. Skipping.");
                return 1;
        }

        if((get_cseq(msg)->method_id)&(METHOD_REGISTER|METHOD_PUBLISH))
                return 1;

        return 0;


Regards,
Brian

Hello Brian,

Module: sip-router
Branch: 3.1
Commit: a72e59d23d4b104af6d7f30d1dc02a5fe175f3af

Also master and 3.0 are checked. the patch is this simple check for 
messages that don't have a correct CSeq header.

Marius

Ok, I checked out the latest 3.1 and it's definitely not included. Will
patch and recompile...

Hi Marius,

I did apply this patch and recompile. I checked the lib folder and date of
topoh changed to compile date.

Another SIP attack and core dump again.

This looks like different memory addresses though.

Hello,

I did some more safety checks. Can you try it again and report if it is

If you get some backtrace anytime is a crash, that will help a lot.

Thanks,
Daniel
