Debian LTS Advisory DLA-3122-1 [email protected]

Package : dovecot
Version : 1:2.3.4.1-5+deb10u7
CVE ID : CVE-2021-33515 CVE-2022-30550

Two security issues were discovered in dovecot: IMAP and POP3 email server.

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.

its security tracker page at:
