| CVE-2016-4983 | 3 Dovecot, Opensuse, Redhat | 4 Dovecot, Leap, Opensuse and 1 more | 2019-11-08 | 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. | |||||
| CVE-2017-2669 | 2 Debian, Dovecot | 2 Debian Linux, Dovecot | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 2019-10-09 | 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 | 2019-10-02 | 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-2019-11500 | 3 Debian, Dovecot, Fedoraproject | 4 Debian Linux, Dovecot, Pigeonhole and 1 more | 2019-09-06 | 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-2019-3814 | 3 Canonical, Dovecot, Opensuse | 3 Ubuntu Linux, Dovecot, Leap | 2019-06-13 | 4.9 MEDIUM | 6.8 MEDIUM |
| 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-2019-7524 | 4 Canonical, Debian, Dovecot and 1 more | 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more | 2019-06-13 | 7.2 HIGH | 7.8 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-2007-2231 | 1 Dovecot | 1 Dovecot | 2018-10-16 | 4.3 MEDIUM | N/A |
| Directory traversal vulnerability in index/mbox/mbox-storage.c in Dovecot before 1.0.rc29, when using the zlib plugin, allows remote attackers to read arbitrary gzipped (.gz) mailboxes (mbox files) via a .. (dot dot) sequence in the mailbox name. | |||||
| CVE-2007-6598 | 1 Dovecot | 1 Dovecot | 2018-10-15 | 6.8 MEDIUM | N/A |
| Dovecot before 1.0.10, with certain configuration options including use of %variables, does not properly maintain the LDAP+auth cache, which might allow remote authenticated users to login as a different user who has the same password. | |||||
| CVE-2008-4578 | 1 Dovecot | 1 Dovecot | 2018-10-11 | 5.0 MEDIUM | N/A |
| The ACL plugin in Dovecot before 1.1.4 allows attackers to bypass intended access restrictions by using the "k" right to create unauthorized "parent/child/child" mailboxes. | |||||
| CVE-2008-1218 | 1 Dovecot | 1 Dovecot | 2018-10-11 | 6.8 MEDIUM | N/A |
| Argument injection vulnerability in Dovecot 1.0.x before 1.0.13, and 1.1.x before 1.1.rc3, when using blocking passdbs, allows remote attackers to bypass the password check via a password containing TAB characters, which are treated as argument delimiters that enable the skip_password_check field to be specified. | |||||
| CVE-2008-1199 | 1 Dovecot | 1 Dovecot | 2018-10-11 | 4.4 MEDIUM | N/A |
| Dovecot before 1.0.11, when configured to use mail_extra_groups to allow Dovecot to create dotlocks in /var/mail, might allow local users to read sensitive mail files for other users, or modify files or directories that are writable by group, via a symlink attack. | |||||
| CVE-2013-6171 | 1 Dovecot | 1 Dovecot | 2018-03-15 | 5.8 MEDIUM | N/A |
| checkpassword-reply in Dovecot before 2.2.7 performs setuid operations to a user who is authenticating, which allows local users to bypass authentication and access virtual email accounts by attaching to the process and using a restricted file descriptor to modify account information in the response to the dovecot-auth server. | |||||
| CVE-2014-3430 | 1 Dovecot | 1 Dovecot | 2017-12-28 | 5.0 MEDIUM | N/A |
| Dovecot 1.1 before 2.2.13 and dovecot-ee before 2.1.7.7 and 2.2.x before 2.2.12.12 does not properly close old connections, which allows remote attackers to cause a denial of service (resource consumption) via an incomplete SSL/TLS handshake for an IMAP/POP3 connection. | |||||
| CVE-2015-3420 | 2 Dovecot, Fedoraproject | 2 Dovecot, Fedora | 2017-10-05 | 4.3 MEDIUM | 5.9 MEDIUM |
| The ssl-proxy-openssl.c function in Dovecot before 2.2.17, when SSLv3 is disabled, allow remote attackers to cause a denial of service (login process crash) via vectors related to handshake failures. | |||||
| CVE-2008-4577 | 1 Dovecot | 1 Dovecot | 2017-09-28 | 6.4 MEDIUM | N/A |
| The ACL plugin in Dovecot before 1.1.4 treats negative access rights as if they are positive access rights, which allows attackers to bypass intended access restrictions. | |||||
| CVE-2007-4211 | 1 Dovecot | 1 Dovecot | 2017-09-28 | 6.0 MEDIUM | N/A |
| The ACL plugin in Dovecot before 1.0.3 allows remote authenticated users with the insert right to save certain flags via a (1) COPY or (2) APPEND command. | |||||
| CVE-2009-3235 | 1 Dovecot | 1 Dovecot | 2017-09-18 | 7.5 HIGH | N/A |
| Multiple stack-based buffer overflows in the Sieve plugin in Dovecot 1.0 before 1.0.4 and 1.1 before 1.1.7, as derived from Cyrus libsieve, allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted SIEVE script, as demonstrated by forwarding an e-mail message to a large number of recipients, a different vulnerability than CVE-2009-2632. | |||||
| CVE-2011-2166 | 1 Dovecot | 1 Dovecot | 2017-08-28 | 6.5 MEDIUM | N/A |
| script-login in Dovecot 2.0.x before 2.0.13 does not follow the user and group configuration settings, which might allow remote authenticated users to bypass intended access restrictions by leveraging a script. | |||||
