{"id":"DEBIAN-CVE-2023-38039","details":"When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API.  However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory.","modified":"2026-09-15T09:02:43.282956655Z","published":"2023-09-15T04:15:10.127Z","upstream":["CVE-2023-38039"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-38039"}],"affected":[{"package":{"name":"curl","ecosystem":"Debian:12","purl":"pkg:deb/debian/curl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.88.1-10+deb12u3"}]}],"versions":["7.88.1-10","7.88.1-10+deb12u1","7.88.1-10+deb12u1~bpo11+1","7.88.1-10+deb12u2","7.88.1-10+deb12u3~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-38039.json"}},{"package":{"name":"curl","ecosystem":"Debian:13","purl":"pkg:deb/debian/curl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-38039.json"}},{"package":{"name":"curl","ecosystem":"Debian:14","purl":"pkg:deb/debian/curl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-38039.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"}]}
