Debian LTS Advisory DLA-3122-1 debian-lts@lists.debian.org

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.
