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 .","published":"2024-02-07T17:15:11.000Z","lastModified":"2026-06-17T07:06:17.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-126","CWE-125"],"affected":["cisco/secure endpoint","cisco/secure endpoint private cloud","fedoraproject/fedora"],"epss":{"score":0.33323,"percentile":0.98375,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 33.3%, higher than 98% of all known CVEs.
