CVE-2021-33515

The submission service in Dovecot before 2.3.15 allows STARTTLS command injection in lib-smtp. Sensitive information can be redirected to an attacker-controlled address.

CVE-2022-30550

When two passdb configuration entries exist with the same driver and args settings, incorrectly applied settings can lead to an unintended security configuration and can permit privilege escalation in certain configurations.

For Debian 10 buster, these problems have been fixed in version 1:2.3.4.1-5+deb10u7.

We recommend that you upgrade your dovecot packages.

For the detailed security status of dovecot please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
