[Linphone-developers] Invalid encoding of STUN ERROR-CODE attribute

[Jeremy Lainé]

Hello,

While investigating a FreeSwitch crash that occurred upon receiving STUN
packets from linphone (as part of the ICE negotiation), I noticed that
linphone was sending malformed STUN packets.

The problem is that the "reason" string (in this case: "Role Conflict")
was not padded to align to a 32-bit boundary.

I have tracked this down to the encode_error_code method in
mediastreamer2. I have submitted a pull request here:

https://github.com/BelledonneCommunications/mediastreamer2/pull/13

Please let me know if I can provide additional information.

Cheers,

Jeremy
