{"id":"DEBIAN-CVE-2026-5440","details":"A memory exhaustion vulnerability exists in the HTTP server due to unbounded use of the `Content-Length` header.  The server allocates memory directly based on the attacker supplied header value without enforcing an upper limit. A crafted HTTP request containing an extremely large `Content-Length` value can trigger excessive memory allocation and server termination, even without sending a request body.","modified":"2026-09-14T17:03:45.659237259Z","published":"2026-04-09T15:16:16.337Z","upstream":["CVE-2026-5440"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-5440"}],"affected":[{"package":{"name":"orthanc","ecosystem":"Debian:12","purl":"pkg:deb/debian/orthanc?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.1+dfsg-2","1.10.1+dfsg-2+deb12u1","1.12.1+dfsg-1","1.12.1+dfsg-2","1.12.1+dfsg-3","1.12.1+dfsg-4","1.12.10+dfsg-1","1.12.10+dfsg-2","1.12.10+dfsg-3","1.12.10+dfsg-4","1.12.10+dfsg-5","1.12.11+dfsg-1","1.12.11+dfsg-2","1.12.11+dfsg-3","1.12.11+dfsg-4","1.12.11+dfsg-5","1.12.11+dfsg-6","1.12.11+dfsg-7","1.12.11+dfsg-8","1.12.2+dfsg-1","1.12.3+dfsg-1","1.12.3+dfsg-2","1.12.4+dfsg-1","1.12.4+dfsg-2","1.12.4+dfsg-3","1.12.4+dfsg-4","1.12.5+dfsg-1","1.12.5+dfsg-2","1.12.6+dfsg-1","1.12.7+dfsg-1","1.12.7+dfsg-2","1.12.7+dfsg-3","1.12.7+dfsg-4","1.12.9+dfsg-1","1.12.9+dfsg-2","1.13.0+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-5440.json"}},{"package":{"name":"orthanc","ecosystem":"Debian:13","purl":"pkg:deb/debian/orthanc?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.10+dfsg-1","1.12.10+dfsg-2","1.12.10+dfsg-3","1.12.10+dfsg-4","1.12.10+dfsg-5","1.12.11+dfsg-1","1.12.11+dfsg-2","1.12.11+dfsg-3","1.12.11+dfsg-4","1.12.11+dfsg-5","1.12.11+dfsg-6","1.12.11+dfsg-7","1.12.11+dfsg-8","1.12.7+dfsg-4","1.12.9+dfsg-1","1.12.9+dfsg-2","1.13.0+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-5440.json"}},{"package":{"name":"orthanc","ecosystem":"Debian:14","purl":"pkg:deb/debian/orthanc?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.12.10+dfsg-4"}]}],"versions":["1.12.10+dfsg-1","1.12.10+dfsg-2","1.12.10+dfsg-3","1.12.7+dfsg-4","1.12.9+dfsg-1","1.12.9+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-5440.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
