Details

It was discovered that Dovecot incorrectly handled certain imap hibernation
commands. A remote authenticated attacker could possibly use this issue to
access other users’ email. This issue only affected Ubuntu 18.04 LTS,
Ubuntu 20.04 LTS, and Ubuntu 20.10. (CVE-2020-24386)

Innokentii Sennovskiy discovered that Dovecot incorrectly handled MIME
parsing. A remote attacker could possibly use this issue to cause Dovecot
to crash, resulting in a denial of service. (CVE-2020-25275)
