{"id":"UBUNTU-CVE-2024-32663","details":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. 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":"2026-05-20T16:08:50.825124054Z","published":"2024-05-07T15:15:00Z","upstream":["CVE-2024-32663"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-32663"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-32663"},{"type":"REPORT","url":"https://github.com/OISF/suricata/security/advisories/GHSA-9jxm-qw9v-266r"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/08d93f7c3762781b743f88f9fdc4389eb9c3eb64"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/c0af92295e833d1db29b184d63cd3b829451d7fd"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/d24b37a103c04bb2667e449e080ba4c8e56bb019"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/e68ec4b227d19498f364a41eb25d3182f0383ca5"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6892"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6900"}],"affected":[{"package":{"name":"suricata","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.8-1build1","2.0.9-1","2.0.10-1","2.0.10-2","2.0.11-1","3.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"suricata","binary_version":"3.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2-2ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"libhtp-0.5.23-1","binary_version":"3.2-2ubuntu3"},{"binary_name":"suricata","binary_version":"3.2-2ubuntu3"},{"binary_name":"suricata-hyperscan","binary_version":"3.2-2ubuntu3"},{"binary_name":"suricata-oinkmaster","binary_version":"3.2-2ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:6.0.4-2","1:6.0.4-3"],"ecosystem_specific":{"binaries":[{"binary_name":"suricata","binary_version":"1:6.0.4-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:7.0.0-2","1:7.0.2-1","1:7.0.2-1build1","1:7.0.3-1build1","1:7.0.3-1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"suricata","binary_version":"1:7.0.3-1build3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:7.0.8-2","1:7.0.10-1"],"ecosystem_specific":{"binaries":[{"binary_name":"suricata","binary_version":"1:7.0.10-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32663.json"}},{"package":{"name":"suricata","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:7.0.10-1","1:8.0.1-3build1","1:8.0.2-1","1:8.0.2-1build1","1:8.0.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1:8.0.3-1","binary_name":"suricata"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-32663.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
