| CVE-2022-30550 | 3 Debian, Dovecot, Redhat | 3 Debian Linux, Dovecot, Enterprise Linux | 2025-05-23 | 8.8 High |
| An issue was discovered in the auth component in Dovecot 2.2 and 2.3 before 2.3.20. When two passdb configuration entries exist with the same driver and args settings, incorrect username_filter and mechanism settings can be applied to passdb definitions. These incorrectly applied settings can lead to an unintended security configuration and can permit privilege escalation in certain configurations. The documentation does not advise against the use of passdb definitions that have the same driver and args settings. One such configuration would be where an administrator wishes to use the same PAM configuration or passwd file for both normal and master users but use the username_filter setting to restrict which of the users is able to be a master user. | ||||
| CVE-2015-3420 | 2 Dovecot, Fedoraproject | 2 Dovecot, Fedora | 2025-04-20 | N/A |
| 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-2016-8652 | 1 Dovecot | 1 Dovecot | 2025-04-20 | N/A |
| The auth component in Dovecot before 2.2.27, when auth-policy is configured, allows a remote attackers to cause a denial of service (crash) by aborting authentication without setting a username. | ||||
| CVE-2014-3430 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-12 | 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-2013-2111 | 1 Dovecot | 1 Dovecot | 2025-04-12 | N/A |
| The IMAP functionality in Dovecot before 2.2.2 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via invalid APPEND parameters. | ||||
| CVE-2011-2166 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-11 | 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. | ||||
| CVE-2010-3780 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-11 | N/A |
| Dovecot 1.2.x before 1.2.15 allows remote authenticated users to cause a denial of service (master process outage) by simultaneously disconnecting many (1) IMAP or (2) POP3 sessions. | ||||
| CVE-2010-3706 | 1 Dovecot | 1 Dovecot | 2025-04-11 | N/A |
| plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving the private namespace of a user, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox. | ||||
| CVE-2010-3779 | 1 Dovecot | 1 Dovecot | 2025-04-11 | N/A |
| Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.beta2 grants the admin permission to the owner of each mailbox in a non-public namespace, which might allow remote authenticated users to bypass intended access restrictions by changing the ACL of a mailbox, as demonstrated by a symlinked shared mailbox. | ||||
| CVE-2010-3707 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-11 | N/A |
| plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving more specific entries that occur after less specific entries, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox. | ||||
| CVE-2011-1929 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-11 | N/A |
| lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message. | ||||
| CVE-2011-2167 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-11 | N/A |
| script-login in Dovecot 2.0.x before 2.0.13 does not follow the chroot configuration setting, which might allow remote authenticated users to conduct directory traversal attacks by leveraging a script. | ||||
| CVE-2011-4318 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-11 | N/A |
| Dovecot 2.0.x before 2.0.16, when ssl or starttls is enabled and hostname is used to define the proxy destination, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate for a different hostname. | ||||
| CVE-2010-3304 | 1 Dovecot | 1 Dovecot | 2025-04-11 | N/A |
| The ACL plugin in Dovecot 1.2.x before 1.2.13 propagates INBOX ACLs to newly created mailboxes in certain configurations, which might allow remote attackers to read mailboxes that have unintended weak ACLs. | ||||
| CVE-2010-0745 | 1 Dovecot | 1 Dovecot | 2025-04-11 | N/A |
| Unspecified vulnerability in Dovecot 1.2.x before 1.2.11 allows remote attackers to cause a denial of service (CPU consumption) via long headers in an e-mail message. | ||||
| CVE-2013-6171 | 1 Dovecot | 1 Dovecot | 2025-04-11 | 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-2009-3897 | 1 Dovecot | 1 Dovecot | 2025-04-09 | 5.5 Medium |
| Dovecot 1.2.x before 1.2.8 sets 0777 permissions during creation of certain directories at installation time, which allows local users to access arbitrary user accounts by replacing the auth socket, related to the parent directories of the base_dir directory, and possibly the base_dir directory itself. | ||||
| CVE-2009-3235 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-09 | 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-2007-6598 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-09 | 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-2007-2231 | 2 Dovecot, Redhat | 2 Dovecot, Enterprise Linux | 2025-04-09 | 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. | ||||
