{"id":"CVE-2017-12374","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 operations (mbox.c operations on bounce messages). If successfully exploited, the ClamAV software could allow a variable pointing to the mail body which could cause a used after being free (use-after-free) instance which may lead to a disruption of services on an affected device to include a denial of service condition.","modified":"2026-04-16T06:15:35.527150555Z","published":"2018-01-26T20:29:00.283Z","related":["SUSE-SU-2018:0254-1","SUSE-SU-2018:0255-1","openSUSE-SU-2024:10685-1"],"references":[{"type":"WEB","url":"https://usn.ubuntu.com/3550-1/"},{"type":"WEB","url":"https://usn.ubuntu.com/3550-2/"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2018/01/msg00035.html"},{"type":"ADVISORY","url":"http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html"},{"type":"FIX","url":"https://bugzilla.clamav.net/show_bug.cgi?id=11939"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cisco-talos/clamav","events":[{"introduced":"0"},{"last_affected":"5ceae552829ee65c9ecff8ff303b1f2ddfd11576"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"0.99.2"}]}}],"versions":["clamav-0.96","clamav-0.96.2","clamav-0.96.3","clamav-0.96.4","clamav-0.96.5","clamav-0.96rc1","clamav-0.96rc2","clamav-0.97","clamav-0.97rc","clamav-0.99.2","merge-llvm-97877","r5076"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-12374.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"7.0"}]}]}}],"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"}]}
