CVE-2008-1199 2 Dovecot, Redhat 2 Dovecot, Enterprise Linux 2026-04-23 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-2009-3897 1 Dovecot 1 Dovecot 2026-04-23 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 2026-04-23 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-2008-5301 1 Dovecot 1 Dovecot 2026-04-23 N/A
Directory traversal vulnerability in the ManageSieve implementation in Dovecot 1.0.15, 1.1, and 1.2 allows remote attackers to read and modify arbitrary .sieve files via a ".." (dot dot) in a script name.
CVE-2008-4577 5 Canonical, Dovecot, Fedoraproject and 2 more 5 Ubuntu Linux, Dovecot, Fedora and 2 more 2026-04-23 7.5 High
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-2008-4870 2 Dovecot, Redhat 2 Dovecot, Enterprise Linux 2026-04-23 N/A
dovecot 1.0.7 in Red Hat Enterprise Linux (RHEL) 5, and possibly Fedora, uses world-readable permissions for dovecot.conf, which allows local users to obtain the ssl_key_password parameter value.
CVE-2008-4578 1 Dovecot 1 Dovecot 2026-04-23 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-2008-4907 1 Dovecot 1 Dovecot 2026-04-23 N/A
The message parsing feature in Dovecot 1.1.4 and 1.1.5, when using the FETCH ENVELOPE command in the IMAP client, allows remote attackers to cause a denial of service (persistent crash) via an email with a malformed From address, which triggers an assertion error, aka "invalid message address parsing bug."
CVE-2008-1218 1 Dovecot 1 Dovecot 2026-04-23 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-2007-6598 2 Dovecot, Redhat 2 Dovecot, Enterprise Linux 2026-04-23 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 2026-04-23 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-2007-4211 2 Dovecot, Redhat 2 Dovecot, Enterprise Linux 2026-04-23 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-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-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-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-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-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-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-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.
