|---|---|---|---|---|---|
| CVE-2020-10957 | 1 Dovecot | 1 Dovecot | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-7524 | 4 Canonical, Debian, Dovecot and 1 more | 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| 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 | 3 Canonical, Dovecot, Opensuse | 3 Ubuntu Linux, Dovecot, Leap | 2024-11-21 | 4.9 MEDIUM | 7.7 HIGH |
| 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-2019-19722 | 2 Dovecot, Fedoraproject | 2 Dovecot, Fedora | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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 | 3 Debian, Dovecot, Fedoraproject | 4 Debian Linux, Dovecot, Pigeonhole and 1 more | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2019-11499 | 3 Dovecot, Fedoraproject, Opensuse | 3 Dovecot, Fedora, Leap | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-11494 | 3 Dovecot, Fedoraproject, Opensuse | 3 Dovecot, Fedora, Leap | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-10691 | 2 Dovecot, Opensuse | 2 Dovecot, Leap | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-2669 | 2 Debian, Dovecot | 2 Debian Linux, Dovecot | 2024-11-21 | 5.0 MEDIUM | 3.7 LOW |
| Dovecot before version 2.2.29 is vulnerable to a denial of service. When 'dict' passdb and userdb were used for user authentication, the username sent by the IMAP/POP3 client was sent through var_expand() to perform %variable expansion. Sending specially crafted %variable fields could result in excessive memory usage causing the process to crash (and restart), or excessive CPU usage causing all authentications to hang. | |||||
| CVE-2017-15132 | 3 Canonical, Debian, Dovecot | 3 Ubuntu Linux, Debian Linux, Dovecot | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in dovecot 2.0 up to 2.2.33 and 2.3.0. An abort of SASL authentication results in a memory leak in dovecot's auth client used by login processes. The leak has impact in high performance configuration where same login processes are reused and can cause the process to crash due to memory exhaustion. | |||||
| CVE-2017-15130 | 3 Canonical, Debian, Dovecot | 3 Ubuntu Linux, Debian Linux, Dovecot | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
| CVE-2017-14461 | 3 Debian, Dovecot, Ubuntu | 3 Debian Linux, Dovecot, Ubuntu | 2024-11-21 | 5.5 MEDIUM | 5.9 MEDIUM |
| A specially crafted email delivered over SMTP and passed on to Dovecot by MTA can trigger an out of bounds read resulting in potential sensitive information disclosure and denial of service. In order to trigger this vulnerability, an attacker needs to send a specially crafted email message to the server. | |||||
| CVE-2016-4983 | 3 Dovecot, Opensuse, Redhat | 4 Dovecot, Leap, Opensuse and 1 more | 2024-11-21 | 2.1 LOW | 3.3 LOW |
| A postinstall script in the dovecot rpm allows local users to read the contents of newly created SSL/TLS key files. | |||||
