{"id":"UBUNTU-CVE-2024-23836","details":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 6.0.16 and 7.0.3, an attacker can craft traffic to cause Suricata to use far more CPU and memory for processing the traffic than needed, which can lead to extreme slow downs and denial of service.  This vulnerability is patched in 6.0.16 or 7.0.3.  Workarounds include disabling the affected protocol app-layer parser in the yaml and reducing the `stream.reassembly.depth` value helps reduce the severity of the issue.","modified":"2026-05-20T16:16:35.836915723Z","published":"2024-02-26T16:27:00Z","upstream":["CVE-2024-23836"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-23836"},{"type":"REPORT","url":"https://github.com/OISF/suricata/security/advisories/GHSA-q33q-45cr-3cpc"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/18841a58da71e735ddf4e52cbfa6989755ecbeb7"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/8efaebe293e2a74c8e323fa85a6f5fadf82801bc"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/2a2120ecf10c5b5713ec2bf59469fe57f7b5b747"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/83c5567ea7b0b28376f57dcfee9c6301448c7bc7"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/b1549e930f6426eeff43f12b672337cbcda566b8"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/97953998d2d60673ed6c30ddfb6a2d59b4230f97"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/e7e28822f473320658d6125f16ac3f0524baff01"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/f9de1cca6182e571f1c02387dca6e695e55608af"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/cd035d59e3df157b606f4fe67324ea8e437be786"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/ce9b90326949c94a46611d6394e28600ee5e8bd5"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6531"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6532"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6540"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6658"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6659"},{"type":"REPORT","url":"https://redmine.openinfosecfoundation.org/issues/6660"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/18841a58da71e735ddf4e52cbfa6989755ecbeb7"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/2a2120ecf10c5b5713ec2bf59469fe57f7b5b747"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/83c5567ea7b0b28376f57dcfee9c6301448c7bc7"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/8efaebe293e2a74c8e323fa85a6f5fadf82801bc"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/97953998d2d60673ed6c30ddfb6a2d59b4230f97"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/b1549e930f6426eeff43f12b672337cbcda566b8"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/cd035d59e3df157b606f4fe67324ea8e437be786"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/ce9b90326949c94a46611d6394e28600ee5e8bd5"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/e7e28822f473320658d6125f16ac3f0524baff01"},{"type":"REPORT","url":"https://github.com/OISF/suricata/commit/f9de1cca6182e571f1c02387dca6e695e55608af"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-23836"}],"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-2024-23836.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/2024/UBUNTU-CVE-2024-23836.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-2024-23836.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://
