CVE-2020-24386 When imap hibernation is active, an attacker (with valid credentials to access the mail server) can cause Dovecot to discover file system directory structures and access other users' emails via specially crafted commands. CVE-2020-25275 Innokentii Sennovskiy reported that the mail delivery and parsing in Dovecot can crash when the 10000th MIME part is message/rfc822 (or if the parent was multipart/digest).
