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. CREATE(Triage): {Link=https://nvd.nist.gov/vuln/detail/CVE-2019-7524 User=admin}
