{"id":"DEBIAN-CVE-2025-64702","details":"quic-go is an implementation of the QUIC protocol in Go. Versions 0.56.0 and below are vulnerable to excessive memory allocation through quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large header field section (many unique header names and/or large values). The implementation builds an http.Header (used on the http.Request and http.Response, respectively), while only enforcing limits on the size of the (QPACK-compressed) HEADERS frame, but not on the decoded header, leading to memory exhaustion. This issue is fixed in version 0.57.0.","modified":"2026-09-01T16:05:48.728344856Z","published":"2025-12-11T21:15:54.707Z","upstream":["CVE-2025-64702"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-64702"}],"affected":[{"package":{"name":"golang-github-lucas-clemente-quic-go","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-github-lucas-clemente-quic-go?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.29.0-1","0.29.2-1","0.29.2-2","0.29.2-3","0.37.0-1","0.37.4-1","0.37.4-1~bpo12+1","0.38.2-1","0.38.2-2","0.46.0-1","0.46.0-2","0.46.0-2~bpo12+1","0.50.0-1","0.50.1-1","0.50.1-2","0.54.0-1","0.54.0-2","0.54.0-3","0.54.1-1","0.55.0-1","0.59.0-1","0.59.0-2","0.59.0-2~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-64702.json"}},{"package":{"name":"golang-github-lucas-clemente-quic-go","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-github-lucas-clemente-quic-go?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.50.1-2","0.54.0-1","0.54.0-2","0.54.0-3","0.54.1-1","0.55.0-1","0.59.0-1","0.59.0-2","0.59.0-2~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-64702.json"}},{"package":{"name":"golang-github-lucas-clemente-quic-go","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-github-lucas-clemente-quic-go?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.59.0-1"}]}],"versions":["0.50.1-2","0.54.0-1","0.54.0-2","0.54.0-3","0.54.1-1","0.55.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-64702.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:L"}]}
