A flaw was found in Asterisk, an Open Source Private Branch Exchange. A buffer overflow vulnerability affects users that use PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. The difference is that this issue is in parsing the query record `parse_query`, while the issue in CVE-2022-24793 is in `parse_rr`. A workaround is to disable DNS resolution in PJSIP config or use an external resolver implementation instead.
