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't affect PJSIP users who do not utilise PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. A patch is available as commit `d1c5e4d` in the `master` branch. A workaround is to disable DNS resolution in PJSIP config (by setting `nameserver_count` to zero) or use an external resolver implementation instead. https://github.com/pjsip/pjproject/commit/d1c5e4da5bae7f220bc30719888bb389c905c0c5 https://www.pjsip.org/pjlib-util/docs/html/group__PJ__DNS__RESOLVER.htm https://github.com/pjsip/pjproject/security/advisories/GHSA-q9cp-8wcq-7pfr https://github.com/pjsip/pjproject/security/advisories/GHSA-p6g5-v97c-w5q4
