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. 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 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.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.02311,"percentile":0.8361,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-120","CWE-122"],"published":"2023-03-14T00:00:00Z","modified":"2026-10-28T10:32:36Z","fixes":[{"ecosystem":"Alpine:v3.18","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"pjproject","fixed_in":["2.13.1-r0"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"asterisk","fixed_in":["1:20.4.0~dfsg+~cs6.13.40431414-1"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"ring","fixed_in":["20230206.0~ds2-1.1+deb12u1"],"sources":["osv"]},{"ecosystem":"Debian:10","package":"asterisk","fixed_in":["1:16.28.0~dfsg-0+deb10u3"],"sources":["osv"]},{"ecosystem":"Debian:11","package":"asterisk","fixed_in":["1:16.28.0~dfsg-0+deb11u3"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:18.04:LTS","package":"ring","fixed_in":["20180228.1.503da2b~ds1-1ubuntu0.1~esm1"],"sources":["osv"]},{"ecosystem":"Ubuntu:20.04:LTS","package":"ring","fixed_in":["20190215.1.f152c98~ds1-1+deb10u2build0.20.04.1"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.18","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.21","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.22","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.13.1-r0"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"asterisk","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:20.4.0~dfsg+~cs6.13.40431414-1"}]}],"versions":["0.1.11-3","0.1.11-3woody1","1:1.0.5-2","1:1.0.5-4","1:1.0.6-1","1:1.0.6-2","1:1.0.7-1","1:1.0.7.dfsg.1-1","1:1.0.7.dfsg.1-2","1:1.0.7.dfsg.1-2sarge1","1:1.0.7.dfsg.1-2sarge2","1:1.0.7.dfsg.1-2sarge3","1:1.0.7.dfsg.1-2sarge4","1:1.0.7.dfsg.1-2sarge5","1:1.0.7.dfsg.1-2sarge6","1:1.0.9.dfsg-1","1:1.0.9.dfsg-3","1:1.0.9.dfsg-4","1:1.0.9.dfsg-5","1:1.0.9.dfsg-6","1:1.2.0-beta1.dfsg-1","1:1.2.0-beta2.dfsg-1","1:1.2.0-beta2.dfsg-2","1:1.2.0-beta2.dfsg-3","1:1.2.0-rc1.dfsg-1","1:1.2.0-rc2.dfsg-1","1:1.2.0.dfsg-1","1:1.2.0.dfsg-2","1:1.2.0.dfsg-3","1:1.2.0.dfsg-4","1:1.2.0.dfsg-5","1:1.2.0.dfsg-6","1:1.2.1.dfsg-1","1:1.2.1.dfsg-2","1:1.2.1.dfsg-3","1:1.2.10.dfsg-1","1:1.2.10.dfsg-1bpo1","1:1.2.10.dfsg-2","1:1.2.10.dfsg-3","1:1.2.11.dfsg-1","1:1.2.12.1.dfsg-1","1:1.2.13~dfsg-1","1:1.2.13~dfsg-2","1:1.2.13~dfsg-2etch1","1:1.2.13~dfsg-2etch2","1:1.2.13~dfsg-2etch3","1:1.2.13~dfsg-2etch4","1:1.2.14~dfsg-1","1:1.2.14~dfsg-2","1:1.2.14~dfsg-3","1:1.2.14~dfsg-4","1:1.2.15~dfsg-1","1:1.2.16~dfsg-1","1:1.2.17~dfsg-1","1:1.2.4.dfsg-1","1:1.2.4.dfsg-2","1:1.2.4.dfsg-3","1:1.2.4.dfsg-4","1:1.2.4.dfsg-5","1:1.2.4.dfsg-6","1:1.2.4.dfsg-6+b1","1:1.2.4.dfsg-7","1:1.2.7.1.dfsg-1","1:1.2.7.1.dfsg-2","1:1.2.7.1.dfsg-3","1:1.2.9.1.dfsg-1","1:1.4.10~dfsg-1","1:1.4.11~dfsg-1","1:1.4.11~dfsg-2","1:1.4.11~dfsg-3","1:1.4.11~dfsg-4","1:1.4.13~dfsg-1","1:1.4.15~dfsg-1","1:1.4.16.2~dfsg-1","1:1.4.16.2~dfsg-2","1:1.4.17~dfsg-1","1:1.4.17~dfsg-2","1:1.4.18.1~dfsg-1","1:1.4.18~dfsg-1","1:1.4.19.1~dfsg-1","1:1.4.20~dfsg-1","1:1.4.21.1~dfsg-1","1:1.4.21.2~dfsg-1","1:1.4.21.2~dfsg-2","1:1.4.21.2~dfsg-3","1:1.4.21.2~dfsg-3+lenny1","1:1.4.21.2~dfsg-3+lenny2","1:1.4.21.2~dfsg-3+lenny2.1","1:1.4.21.2~dfsg-3+lenny3","1:1.4.21.2~dfsg-3+lenny5","1:1.4.21.2~dfsg-3+lenny6","1:1.4.21.2~dfsg-3.1","1:1.4.2~dfsg-1","1:1.4.2~dfsg-2","1:1.4.2~dfsg-3","1:1.4.2~dfsg-4","1:1.4.2~dfsg-5","1:1.4.3~dfsg-1","1:1.4.4~dfsg-1","1:1.4.4~dfsg-2","1:1.4.4~dfsg-3","1:1.4.5~dfsg-1","1:1.4.6~dfsg-1","1:1.4.8~dfsg-1",
