{"id":"UBUNTU-CVE-2025-59148","details":"Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 8.0.0 and below incorrectly handle the entropy keyword when not anchored to a \"sticky\" buffer, which can lead to a segmentation fault. This issue is fixed in version 8.0.1. To workaround this issue, users can disable rules using the entropy keyword, or validate they are anchored to a sticky buffer.","modified":"2026-05-20T16:23:38.393455113Z","published":"2025-10-01T20:18:00Z","upstream":["CVE-2025-59148"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-59148"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-59148"},{"type":"REPORT","url":"https://github.com/OISF/suricata/security/advisories/GHSA-5qf6-92xg-3rr3"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/9f32550e18f97ea5d610dd7c36aab0ba142c096c"},{"type":"REPORT","url":"https://forum.suricata.io/t/suricata-8-0-1-and-7-0-12-released/6018"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/7838"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/9f32550e18f97ea5d610dd7c36aab0ba142c096c"}],"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/2025/UBUNTU-CVE-2025-59148.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_version":"3.2-2ubuntu3","binary_name":"suricata-oinkmaster"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59148.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/2025/UBUNTU-CVE-2025-59148.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_version":"1:7.0.3-1build3","binary_name":"suricata"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59148.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_version":"1:7.0.10-1","binary_name":"suricata"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59148.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_name":"suricata","binary_version":"1:8.0.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59148.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":"Ubuntu","score":"medium"}]}
