PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, there is an out-of-bounds read when parsing a malformed Content-ID URI in SIP multipart message body. Insufficient length validation can cause reads beyond the intended buffer bounds. This vulnerability is fixed in 2.17.
