{"id":"CVE-2026-60108","summary":"Zeek \u003c 8.0.9 Uncontrolled Memory Consumption DoS via FTP Analyzer","details":"Zeek before 8.0.9 contains an uncontrolled memory consumption vulnerability in the FTP analyzer that allows unauthenticated remote attackers to cause process termination by sending a crafted FTP control session negotiating AUTH GSSAPI followed by a large ADAT control line. Attackers can exploit the NVT_Analyzer component's lack of a maximum line length check, causing it to continuously double its internal buffer without bounds during base64 decoding of an attacker-controlled ADAT token, resulting in denial of service of the Zeek sensor.","modified":"2026-08-12T03:51:09.274956678Z","published":"2026-07-09T14:16:57.988Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/60xxx/CVE-2026-60108.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/60xxx/CVE-2026-60108.json"},{"type":"ADVISORY","url":"https://github.com/zeek/zeek/releases/tag/v8.0.9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60108"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/zeek-uncontrolled-memory-consumption-dos-via-ftp-analyzer"},{"type":"FIX","url":"https://github.com/zeek/zeek/commit/93ff6950a90cfa9d00c1062cde429313a0402a01"},{"type":"PACKAGE","url":"https://github.com/zeek/zeek"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zeek/zeek","events":[{"introduced":"0"},{"fixed":"9abee105a8259b65e350d57b68d03c6db00fe3a8"},{"fixed":"93ff6950a90cfa9d00c1062cde429313a0402a01"}],"database_specific":{"cpe":"cpe:2.3:a:zeek:zeek:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"8.0.9"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v8.0.8","v8.0.7","v8.0.6","lts","v8.0.5","v8.0.4","v8.0.3","v8.0.2","v8.0.1","v8.0.0","v8.0.0-rc2","v8.0.0-rc1","v8.0.0-dev","v7.2.0-dev","v7.1.0-dev","v7.0.0-dev","v6.2.0-dev","v6.1.0-dev","v6.0.0-dev","v5.2.0-dev","v5.1.0-dev","v5.0.0-dev","v4.2.0-dev","v4.1.0-dev","v3.3.0-dev","v3.2.0-dev","v3.1.0-dev","v2.6","release","v2.6-beta3","beta","v2.6-beta2","v2.5","v2.5-beta2","v2.5-beta","v2.4","v2.4-beta","v2.3","v2.3-beta","v2.2","v2.2-beta","v2.1","v1.1","v2.1-beta","v2.0","v2.0-beta","v2.0-beta-pre","v1.6-dev"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-60108.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
