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.
