> There is logic in res_rtp_asterisk which handles RTCP RR/SR record report blocks.  This code was originally written to handle a single RR/SR report but during HEP work the code was changed so multiple RR/SR reports could be handled.  However, report_counter is not reset between processing RR/SR records which can result in writing outside of allocated memory on the next RR/SR record in the packet.
