Re: [Linphone-developers] Linphone Desktop causes crash on text message when LIME is set to preferred

[Sylvain Berfini]

Hi Felix,

Thanks for reporting this issue, it is now fixed.

Also there was a problem with the Preferred policy causing it to behave exactly like it was Mandatory that I also fixed.

Best regards.

Steps to reproduce (Tested on SuseLeap 42.2):

 

-Start linphone desktop version

-set network LIME to preferred

-Type text message to a recipient that has no encryption token.

-click send button

 

Thread 1 "linphone" received signal SIGSEGV, Segmentation fault.
0x00007ffff090e960 in belle_sip_header_address_get_uri () from lib64/libbellesip.so.0

 

The cause is in chat.c  line 420: If the message cannot be encrypted,  _linphone_chat_room_send_message returns immediately

and leaves msg->from as a NULL pointer, because line 450 is never reached.

 

Later, belle_sip_header_address_get_uri dereferences this NULL pointer, causing the SIGSEGV.
