| CVE-2020-12100 | Hig | 7.5 | < 2.4.0-1.1 | 2.4.0-1.1 | Aug 12, 2020 | In Dovecot before 2.3.11.3, uncontrolled recursion in submission, lmtp, and lda allows remote attackers to cause a denial of service (resource consumption) via a crafted e-mail message with deeply nested MIME parts. | |
| CVE-2020-10967 | Med | 5.3 | < 2.4.0-1.1 | 2.4.0-1.1 | May 18, 2020 | In Dovecot before 2.3.10.1, remote unauthenticated attackers can crash the lmtp or submission process by sending mail with an empty localpart. | |
| CVE-2020-10958 | Med | 5.3 | < 2.4.0-1.1 | 2.4.0-1.1 | May 18, 2020 | In Dovecot before 2.3.10.1, a crafted SMTP/LMTP message triggers an unauthenticated use-after-free bug in submission-login, submission, or lmtp, and can lead to a crash under circumstances involving many newlines after a command. | |
| CVE-2020-10957 | Hig | 7.5 | < 2.4.0-1.1 | 2.4.0-1.1 | May 18, 2020 | In Dovecot before 2.3.10.1, unauthenticated sending of malformed parameters to a NOOP command causes a NULL Pointer Dereference and crash in submission-login, submission, or lmtp. | |
| CVE-2020-7957 | Med | 5.3 | < 2.4.0-1.1 | 2.4.0-1.1 | Feb 12, 2020 | The IMAP and LMTP components in Dovecot 2.3.9 before 2.3.9.3 mishandle snippet generation when many characters must be read to compute the snippet and a trailing > character exists. This causes a denial of service in which the recipient cannot read all of their messages. | |
| CVE-2020-7046 | Hig | 7.5 | < 2.4.0-1.1 | 2.4.0-1.1 | Feb 12, 2020 | lib-smtp in submission-login and lmtp in Dovecot 2.3.9 before 2.3.9.3 mishandles truncated UTF-8 data in command parameters, as demonstrated by the unauthenticated triggering of a submission-login infinite loop. | |
| CVE-2019-19722 | Med | 5.3 | < 2.4.0-1.1 | 2.4.0-1.1 | Dec 13, 2019 | In Dovecot before 2.3.9.2, an attacker can crash a push-notification driver with a crafted email when push notifications are used, because of a NULL Pointer Dereference. The email must use a group address as either the sender or the recipient. | |
| CVE-2019-11500 | Cri | 9.8 | < 2.4.0-1.1 | 2.4.0-1.1 | Aug 29, 2019 | In Dovecot before 2.2.36.4 and 2.3.x before 2.3.7.2 (and Pigeonhole before 0.5.7.2), protocol processing can fail for quoted strings. This occurs because '\0' characters are mishandled, and can lead to out-of-bounds writes and remote code execution. | |
| CVE-2019-11494 | Hig | 7.5 | < 2.4.0-1.1 | 2.4.0-1.1 | May 8, 2019 | In the IMAP Server in Dovecot 2.3.3 through 2.3.5.2, the submission-login service crashes when the client disconnects prematurely during the AUTH command. | |
| CVE-2019-11499 | Hig | 7.5 | < 2.4.0-1.1 | 2.4.0-1.1 | May 8, 2019 | In the IMAP Server in Dovecot 2.3.3 through 2.3.5.2, the submission-login component crashes if AUTH PLAIN is attempted over a TLS secured channel with an unacceptable authentication message. | |
| CVE-2019-10691 | Hig | 7.5 | < 2.4.0-1.1 | 2.4.0-1.1 | Apr 24, 2019 | The JSON encoder in Dovecot before 2.3.5.2 allows attackers to repeatedly crash the authentication service by attempting to authenticate with an invalid UTF-8 sequence as the username. | |
| CVE-2019-7524 | Hig | 8.8 | < 2.4.0-1.1 | 2.4.0-1.1 | Mar 28, 2019 | In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components. | |
| CVE-2019-3814 | Hig | 7.7 | < 2.4.0-1.1 | 2.4.0-1.1 | Mar 27, 2019 | It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users. | |
| CVE-2017-15130 | Med | 5.9 | < 2.4.0-1.1 | 2.4.0-1.1 | Mar 2, 2018 | A denial of service flaw was found in dovecot before 2.2.34. An attacker able to generate random SNI server names could exploit TLS SNI configuration lookups, leading to excessive memory usage and the process to restart. |
