{"id":"UBUNTU-CVE-2026-63449","details":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SIP parser in rust/src/sip/parser.rs stores request and response body lengths in 16-bit fields. A SIP body larger than 65,536 bytes can truncate the length and prevent frame:request.body or frame:response.body from exposing the complete body to inspection, allowing content in the omitted portion to evade frame-based detection. This issue is fixed in version 8.0.6.","modified":"2026-09-21T21:39:52.851020472Z","published":"2026-09-21T00:00:00Z","upstream":["CVE-2026-63449"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-63449"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-63449"},{"type":"REPORT","url":"https://github.com/OISF/suricata/security/advisories/GHSA-prqx-q74v-wxhv"},{"type":"REPORT","url":"https://github.com/OISF/suricata/pull/15807"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/499995bf0e5eab34b647ec1024ce65d72c411816"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/6f87930aff1e2294e46289cb9cbf4d96d79a209a"},{"type":"REPORT","url":"https://github.com/OISF/suricata/releases/tag/suricata-8.0.6"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/8582"}],"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/2026/UBUNTU-CVE-2026-63449.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/2026/UBUNTU-CVE-2026-63449.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/2026/UBUNTU-CVE-2026-63449.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/2026/UBUNTU-CVE-2026-63449.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/2026/UBUNTU-CVE-2026-63449.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
