{"id":"CVE-2017-12378","url":"https://www.cyber-defence.io/tools/cve/CVE-2017-12378","generatedAt":"2026-10-28T20:11:32.448Z","title":"ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.","description":"ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms of .tar (Tape Archive) files sent to an affected device. A successful exploit could cause a checksum buffer over-read condition when ClamAV scans the malicious .tar file, potentially allowing the attacker to cause a DoS condition on the affected device.","published":"2018-01-26T20:29:01.000Z","lastModified":"2026-06-17T01:03:15.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.0","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},"cwe":["CWE-125"],"affected":["debian/debian linux","clamav/clamav"],"epss":{"score":0.02793,"percentile":0.86362,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.04007,"percentile":0.90122},{"date":"2026-09-22","score":0.02793,"percentile":0.85812}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (2.79%).
