Public bug reported:
asterisk 1:13.1.0~dfsg-1.1ubuntu4
lsb_release -rd:
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Bug details:
============
when dialing a h264 video sip device (Grandstream GXV3674_FHD_VF 1.0.3.17)
asterisk crashes with a core dump:
Connected to Asterisk 13.1.0~dfsg-1.1ubuntu4 currently running on samson (pid =
29051)
samson*CLI> console dial waldorf@Phones
-- Executing [waldorf@Phones:1] Dial("Console/default", "SIP/waldorf,60")
in new stack
== Using SIP VIDEO CoS mark 6
== Using SIP RTP CoS mark 5
-- Called SIP/waldorf
-- SIP/waldorf-00000000 is ringing
samson*CLI>
Disconnected from Asterisk server
Asterisk cleanly ending (0).
Executing last minute cleanups
Analysis:
=========
gdb reveals that the module "res_format_attr_h264.so" is resposible due to a
memory allocation failure while examining tokens of the "sprop-parameter-sets"
string in the SIP header.
Proposed Solution:
==================
This bug is already fixed by 2 small patches included in a more recenent
versions of "res/res_format_attr_h264.c"
https://issues.asterisk.org/jira/browse/ASTERISK-24616
Crash in res_format_attr_h264 due to invalid string copy
https://issues.asterisk.org/jira/browse/ASTERISK-25573
[patch] H.264 format attribute module: resets whole SDP
This fixed version of "res/res_format_attr_h264.c" is included e.g. in
asterisk (1:13.13.1~dfsg-4ubuntu1) zesty.
Fixed+Tested:
=============
I tested by rebuiling asterisk 1:13.1.0~dfsg-1.1ubuntu4 packages with the
"res/res_format_attr_h264.c" taken from asterisk 1:13.13.1~dfsg-4ubuntu1 and
could connect to the sip device without any problems.
I would be great, if you could add this patch into asterisk
1:13.1.0~dfsg-1.1ubuntu4, since I don't want to use self built debs on a
16.4 LTS production system.
Thanks a lot
Jörg
