{"id":"UBUNTU-CVE-2019-7524","details":"In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components.","modified":"2026-04-22T12:21:43.679500Z","published":"2019-03-29T00:00:00Z","related":["USN-3928-1"],"upstream":["CVE-2019-7524"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-7524"},{"type":"REPORT","url":"https://www.dovecot.org/pipermail/dovecot-news/2019-March/000403.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3928-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-7524"}],"affected":[{"package":{"name":"dovecot","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/dovecot@1:2.2.9-1ubuntu2.6?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:2.2.9-1ubuntu2.6"}]}],"versions":["1:2.1.7-7ubuntu3","1:2.2.9-1ubuntu1","1:2.2.9-1ubuntu2","1:2.2.9-1ubuntu2.1","1:2.2.9-1ubuntu2.3","1:2.2.9-1ubuntu2.4","1:2.2.9-1ubuntu2.5"],"ecosystem_specific":{"binaries":[{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-core"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-gssapi"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-imapd"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-ldap"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-lmtpd"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-managesieved"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-mysql"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-pgsql"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-pop3d"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-sieve"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-solr"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"dovecot-sqlite"},{"binary_version":"1:2.2.9-1ubuntu2.6","binary_name":"mail-stack-delivery"}],"availability":"No
