{"id":"UBUNTU-CVE-2023-20212","details":"A vulnerability in the AutoIt module 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 a logic error in the memory management of an affected device. An attacker could exploit this vulnerability by submitting a crafted AutoIt file to be scanned by ClamAV on the affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to restart unexpectedly, resulting in a DoS condition.","modified":"2025-07-16T07:45:35.957499Z","published":"2023-08-18T20:15:00Z","withdrawn":"2025-07-18T16:54:17Z","upstream":["CVE-2023-20212"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-20212"},{"type":"REPORT","url":"https://blog.clamav.net/2023/07/2023-08-16-releases.html"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-20212"}],"affected":[{"package":{"name":"clamav","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/clamav@0.103.8+dfsg-0ubuntu0.20.04.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.103.8+dfsg-0ubuntu0.20.04.1"}]}],"versions":["0.101.4+dfsg-1ubuntu1","0.102.1+dfsg-1ubuntu1","0.102.1+dfsg-2ubuntu1","0.102.1+dfsg-2ubuntu2","0.102.2+dfsg-1ubuntu1","0.102.2+dfsg-2ubuntu1","0.102.3+dfsg-0ubuntu0.20.04.1","0.102.4+dfsg-0ubuntu0.20.04.1","0.103.2+dfsg-0ubuntu0.20.04.1","0.103.2+dfsg-0ubuntu0.20.04.2","0.103.5+dfsg-1~20.04.1","0.103.6+dfsg-0ubuntu0.20.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"clamav","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1","binary_name":"clamav-base"},{"binary_name":"clamav-daemon","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"clamav-daemon-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1","binary_name":"clamav-dbgsym"},{"binary_name":"clamav-docs","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"clamav-freshclam","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"clamav-freshclam-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1","binary_name":"clamav-milter"},{"binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1","binary_name":"clamav-milter-dbgsym"},{"binary_name":"clamav-testfiles","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"clamdscan","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"clamdscan-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"libclamav-dev","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"libclamav9","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"},{"binary_name":"libclamav9-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.20.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-20212.json"}},{"package":{"name":"clamav","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/clamav@0.103.8+dfsg-0ubuntu0.22.04.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.103.8+dfsg-0ubuntu0.22.04.1"}]}],"versions":["0.103.3+dfsg-1","0.103.4+dfsg-1","0.103.4+dfsg-1build1","0.103.5+dfsg-1","0.103.6+dfsg-0ubuntu0.22.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"clamav","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-base","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-daemon","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-daemon-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-docs","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1","binary_name":"clamav-freshclam"},{"binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1","binary_name":"clamav-freshclam-dbgsym"},{"binary_name":"clamav-milter","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-milter-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamav-testfiles","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamdscan","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"clamdscan-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"libclamav-dev","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"libclamav9","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"},{"binary_name":"libclamav9-dbgsym","binary_version":"0.103.8+dfsg-0ubuntu0.22.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-20212.json"}}],"schema_version":"1.7.3","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"}]}
