crafted EXE file.","modified":"2026-02-04T04:03:44.552647Z","published":"2018-10-08T00:00:00Z","related":["USN-3789-1","USN-3789-2"],"upstream":["CVE-2018-15378"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-15378"},{"type":"REPORT","url":"https://blog.clamav.net/2018/10/clamav-01002-has-been-released.html"},{"type":"REPORT","url":"http://lists.clamav.net/pipermail/clamav-announce/2018/000033.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3789-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3789-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-15378"}],"affected":[{"package":{"name":"clamav","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/clamav@0.100.2+dfsg-1ubuntu0.14.04.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.100.2+dfsg-1ubuntu0.14.04.1"}]}],"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","0.99.3+addedllvm-0ubuntu0.14.04.1","0.99.4+addedllvm-0ubuntu0.14.04.1","0.100.1+dfsg-1ubuntu0.14.04.1","0.100.1+dfsg-1ubuntu0.14.04.2","0.100.1+dfsg-1ubuntu0.14.04.3","0.100.1+dfsg-1ubuntu0.14.04.4"],"ecosystem_specific":{"binaries":[{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav-base"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav-daemon"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav-docs"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav-freshclam"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav-milter"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"clamav-testfiles"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"libclamav-dev"},{"binary_version":"0.100.2+dfsg-1ubuntu0.14.04.1","binary_name":"libclamav7"}],"availability":"No
