{"id":"UBUNTU-CVE-2024-20290","details":"A vulnerability in the OLE2 file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.   This vulnerability is due to an incorrect check for end-of-string values during scanning, which may result in a heap buffer over-read. 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.   For a description of this vulnerability, see the ClamAV blog .","modified":"2026-04-22T14:38:13.898484Z","published":"2024-02-07T17:15:00Z","related":["USN-6636-1"],"upstream":["CVE-2024-20290"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-20290"},{"type":"REPORT","url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-clamav-hDffu6t"},{"type":"REPORT","url":"https://blog.clamav.net/2023/11/clamav-130-122-105-released.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6636-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-20290"}],"affected":[{"package":{"name":"clamav","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/clamav@1.0.5+dfsg-1ubuntu1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.5+dfsg-1ubuntu1"}]}],"versions":["1.0.2+dfsg-1ubuntu1","1.0.3+dfsg-2ubuntu1","1.0.4+dfsg-0ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"clamav","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_name":"clamav-base","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_version":"1.0.5+dfsg-1ubuntu1","binary_name":"clamav-daemon"},{"binary_name":"clamav-docs","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_name":"clamav-freshclam","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_name":"clamav-milter","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_name":"clamav-testfiles","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_name":"clamdscan","binary_version":"1.0.5+dfsg-1ubuntu1"},{"binary_name":"libclamav11","binary_version":"1.0.5+dfsg-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-20290.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
