{"id":"UBUNTU-CVE-2017-12375","details":"The 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 a lack of input validation checking mechanisms during certain mail parsing functions (the rfc2047 function in mbox.c). An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition on an affected device.","modified":"2026-04-22T12:00:08.943116Z","published":"2018-01-29T00:00:00Z","related":["USN-3550-1","USN-3550-2"],"upstream":["CVE-2017-12375"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-12375"},{"type":"REPORT","url":"http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3550-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3550-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-12375"}],"affected":[{"package":{"name":"clamav","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/clamav@0.99.3+addedllvm-0ubuntu0.14.04.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.99.3+addedllvm-0ubuntu0.14.04.1"}]}],"versions":["0.97.8+dfsg-1ubuntu4","0.97.8+dfsg-1ubuntu5","0.98.1+dfsg-1ubuntu4","0.98.1+dfsg-1ubuntu5","0.98.1+dfsg-2ubuntu2","0.98.1+dfsg-4ubuntu1","0.98.1+dfsg-4ubuntu1.1","0.98.5+addedllvm-0ubuntu0.14.04.1","0.98.6+dfsg-0ubuntu0.14.04.1","0.98.7+dfsg-0ubuntu0.14.04.1","0.99.2+addedllvm-0ubuntu0.14.04.1","0.99.2+addedllvm-0ubuntu0.14.04.2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"clamav","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"clamav-base","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"clamav-daemon","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"clamav-docs","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"clamav-freshclam","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"clamav-milter","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"clamav-testfiles","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"},{"binary_name":"libclamav7","binary_version":"0.99.3+addedllvm-0ubuntu0.14.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-12375.json"}},{"package":{"name":"clamav","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/clamav@0.99.3+addedllvm-0ubuntu0.16.04.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.99.3+addedllvm-0ubuntu0.16.04.1"}]}],"versions":["0.98.7+dfsg-0ubuntu4","0.98.7+dfsg-0ubuntu5","0.99+dfsg-1ubuntu1","0.99+dfsg-1ubuntu1.1","0.99+dfsg-1ubuntu1.2","0.99.2+dfsg-0ubuntu0.16.04.1","0.99.2+dfsg-0ubuntu0.16.04.2","0.99.2+dfsg-0ubuntu0.16.04.3"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"clamav","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamav-base","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamav-daemon","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamav-docs","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamav-freshclam","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamav-milter","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamav-testfiles","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"clamdscan","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"},{"binary_name":"libclamav7","binary_version":"0.99.3+addedllvm-0ubuntu0.16.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-12375.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
