{"id":"DEBIAN-CVE-2025-32743","details":"In ConnMan through 1.44, the lookup string in ns_resolv in dnsproxy.c can be NULL or an empty string when the TC (Truncated) bit is set in a DNS response. This allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code, because those lookup values lead to incorrect length calculations and incorrect memcpy operations.","modified":"2026-09-01T20:05:45.949085760Z","published":"2025-04-10T14:15:29.740Z","upstream":["CVE-2025-32743"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-32743"}],"affected":[{"package":{"name":"connman","ecosystem":"Debian:12","purl":"pkg:deb/debian/connman?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.41-3","1.42-1","1.42-2","1.42-3","1.42-4","1.42-5","1.43-1","1.44-1","1.44-2","1.44-3","1.45-1","1.45-2","1.45-3","2.0-1","2.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-32743.json"}},{"package":{"name":"connman","ecosystem":"Debian:13","purl":"pkg:deb/debian/connman?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.44-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-32743.json"}},{"package":{"name":"connman","ecosystem":"Debian:14","purl":"pkg:deb/debian/connman?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.44-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-32743.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
