{"id":"DEBIAN-CVE-2018-14767","details":"In Kamailio before 5.0.7 and 5.1.x before 5.1.4, a crafted SIP message with a double \"To\" header and an empty \"To\" tag causes a segmentation fault and crash. The reason is missing input validation in the \"build_res_buf_from_sip_req\" core function. This could result in denial of service and potentially the execution of arbitrary code.","modified":"2026-09-01T20:03:55.388074692Z","published":"2018-07-31T06:29:00.227Z","upstream":["CVE-2018-14767"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-14767"}],"affected":[{"package":{"name":"kamailio","ecosystem":"Debian:12","purl":"pkg:deb/debian/kamailio?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-14767.json"}},{"package":{"name":"kamailio","ecosystem":"Debian:13","purl":"pkg:deb/debian/kamailio?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-14767.json"}},{"package":{"name":"kamailio","ecosystem":"Debian:14","purl":"pkg:deb/debian/kamailio?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.1.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-14767.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
