Prior to 7.0.5 and 6.0.19, a small amount of HTTP/2 traffic can lead to Suricata using a large amount of memory. The issue has been addressed in Suricata 7.0.5 and 6.0.19. Workarounds include disabling the HTTP/2 parser and reducing `app-layer.protocols.http2.max-table-size` value (default is 65536).","modified":"2026-11-03T06:32:07.199616266Z","published":"2024-05-07T15:15:08.713Z","upstream":["CVE-2024-32663"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-32663"}],"affected":[{"package":{"name":"suricata","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/suricata?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"7.0.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/suricata?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"7.0.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/suricata?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"7.0.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/suricata?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"7.0.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/suricata?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"7.0.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-32663.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
