An attacker could exploit this vulnerability by submitting a crafted file containing OLE2 content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software and consuming available system resources.\r\n\r For a description of this vulnerability, see the ClamAV blog .","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-125","CWE-126"],"references":["https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5FXZYVDNV66RNMNVJOHAJAYRZV4U64CQ/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6MUDUPAHAAV6FPB2C2QIQCFJ4SHYBOTY/","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-clamav-hDffu6t","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5FXZYVDNV66RNMNVJOHAJAYRZV4U64CQ/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6MUDUPAHAAV6FPB2C2QIQCFJ4SHYBOTY/"],"products":["cisco:secure_endpoint","cisco:secure_endpoint_private_cloud","fedoraproject:fedora"],"source":"nvd","synced_at":"2026-10-19T21:44:57.175229480+00:00"},"epss":{"cve":"CVE-2024-20290","score":0.33323,"percentile":0.98373,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
