  "title": "asterisk: PJSIP is a free and open source multimedia communication library written in C",
  "description": "PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.13 and prior affects applications that use PJSIP DNS resolver. It doesn\u0027t affect PJSIP users who do not utilise PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. The difference is that this issue is in parsing the query record \u0060parse_query()\u0060, while the issue in CVE-2022-24793 is in \u0060parse_rr()\u0060. A patch is available as commit \u0060d1c5e4d\u0060 in the \u0060master\u0060 branch. A workaround is to disable DNS resolution in PJSIP config (by setting \u0060nameserver_count\u0060 to zero) or use an external resolver implementation instead.",
