In versions 2.11.1 and prior, parsing an incoming SIP message that contains a malformed multipart can potentially cause out-of-bound read access. This issue affects all PJSIP users that accept SIP multipart. The patch is available as commit in the `master` branch. There are no known workarounds.","severity":{"version":"3.1","score":9.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","level":"critical","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.04357,"percentile":0.91308,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-125"],"published":"2022-01-27T00:00:00Z","modified":"2026-11-03T07:18:33Z","fixes":[{"ecosystem":"Alpine:v3.16","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"pjproject","fixed_in":["2.12-r0"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"asterisk","fixed_in":["1:18.10.1~dfsg+~cs6.10.40431411-1"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"ring","fixed_in":["20230206.0~ds1-1"],"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:v3.16","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.17","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.18","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.21","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.22","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"pjproject","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.12-r0"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"asterisk","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:18.10.1~dfsg+~cs6.10.40431411-1"}]}],"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+l
