[sr-dev] [tracker] Task opened: Segfault in ims_auth's ims_proxy_authenticate function when IMPU != IMPI (Attachment added)

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Camille Oudot (coudot) Attached to Project - sip-router Summary - Segfault in ims_auth's ims_proxy_authenticate function when IMPU != IMPI Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - All Severity - Medium Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - If a client sends an INVITE with no Proxy-Authorization header, and this request is challenged using ims_proxy_authenticate(), ims_auth module tries to use the address in From header as IMPI for the MAR diameter request. When IMPI != IMPU, the HSS replies with an error code since the user cannot be found. In that case the SIP-Auth-Data-Item AVP isn't found in the MAA answer, and avlist is never initialized in async_cdp_callback(). Adding a safety check in the "done" section prevented the crash to occur (see attached patch). One or more files have been attached.
