The vulnerability is due to improper buffer size tracking that may result in a heap buffer over-read. An attacker could exploit this vulnerability by sending a crafted PDF file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash, resulting in a denial of service condition." } ] }, "generator": { "engine": "Vulnogram 0.0.9" }, "impact": { "cvss": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-20 Improper Input Validation" } ] } ] }, "references": { "reference_data": [ { "name": "https://blog.clamav.net/2021/04/clamav-01032-security-patch-release.html", "refsource": "CISCO", "url": "https://blog.clamav.net/2021/04/clamav-01032-security-patch-release.html" } ] }, "source": { "advisory": "https://blog.clamav.net/2021/04/clamav-01032-security-patch-release.html", "discovery": "UNKNOWN" } }
