{"id":"ALPINE-CVE-2022-24793","details":"PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.12 and prior affects applications that use PJSIP DNS resolution. It doesn't affect PJSIP users who utilize an external resolver. This vulnerability is related to CVE-2023-27585. The difference is that this issue is in parsing the query record `parse_rr()`, while the issue in CVE-2023-27585 is in `parse_query()`. A patch is available in the `master` branch of the `pjsip/pjproject` GitHub repository. A workaround is to disable DNS resolution in PJSIP config (by setting `nameserver_count` to zero) or use an external resolver instead.","modified":"2025-12-03T22:50:01.887806Z","published":"2022-04-06T14:15:08.087Z","upstream":["CVE-2022-24793"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-24793"}],"affected":[{"package":{"name":"pjproject","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12.1-r0"}]}],"versions":["1.0.1-r0","1.10-r0","1.4-r0","1.4-r1","1.6-r0","1.6-r1","1.6-r2","2.0-r0","2.1-r0","2.11-r0","2.11.1-r0","2.11.1-r1","2.11.1-r2","2.12-r0","2.2-r0","2.2.1-r0","2.3-r0","2.4-r0","2.4.5-r0","2.5.5-r0","2.5.5-r1","2.5.5-r2","2.5.5-r3","2.5.5-r4","2.7.2-r0","2.7.2-r1","2.7.2-r2","2.7.2-r3","2.7.2-r4","2.8-r0","2.9-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-24793.json"}},{"package":{"name":"pjproject","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/pjproject?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[
