{"id":"UBUNTU-CVE-2025-59147","details":"Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Versions 7.0.11 and below, as well as 8.0.0, are vulnerable to detection bypass when crafted traffic sends multiple SYN packets with different sequence numbers within the same flow tuple, which can cause Suricata to fail to pick up the TCP session. In IDS mode this can lead to a detection and logging bypass. In IPS mode this will lead to the flow getting blocked. This issue is fixed in versions 7.0.12 and 8.0.1.","modified":"2026-10-17T12:52:23.037251930Z","published":"2025-10-01T20:18:00Z","upstream":["CVE-2025-59147"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-59147"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-59147"},{"type":"REPORT","url":"https://github.com/OISF/suricata/security/advisories/GHSA-v8hv-6v7x-4c2r"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/be6315dba0d9101b11d16e9dacfe2822b3792f1b"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/e91b03c90385db15e21cf1a0e85b921bf92b039e"},{"type":"REPORT","url":"https://forum.suricata.io/t/suricata-8-0-1-and-7-0-12-released/6018"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/be6315dba0d9101b11d16e9dacfe2822b3792f1b"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/e91b03c90385db15e21cf1a0e85b921bf92b039e"}],"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_version":"3.0-1","binary_name":"suricata"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59147.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_version":"3.2-2ubuntu3","binary_name":"suricata-hyperscan"},{"binary_name":"suricata-oinkmaster","binary_version":"3.2-2ubuntu3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59147.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_version":"1:6.0.4-3","binary_name":"suricata"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59147.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/2025/UBUNTU-CVE-2025-59147.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/2025/UBUNTU-CVE-2025-59147.json"}},{"package":{"name":"suricata","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/suricata?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:8.0.3-1","1:8.0.5-1","1:8.0.6-1"],"ecosystem_specific":{"binaries":[{"binary_name":"suricata","binary_version":"1:8.0.6-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-59147.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/2025/UBUNTU-CVE-2025-59147.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:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
