- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3122-1 [email protected] https://www.debian.org/lts/security/ Anton Gladky September 27, 2022 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

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.

For the detailed security status of dovecot please refer to its security tracker page at:
