2019-11-05 CVE-2016-4983 A postinstall script in the dovecot rpm allows local users to read the contents of newly created SSL/TLS key files. Dovecot, Leap, Opensuse, Enterprise_linux N/A
2018-06-21 CVE-2017-2669 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. Debian_linux, Dovecot 7.5
2018-01-25 CVE-2017-15132 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. Ubuntu_linux, Debian_linux, Dovecot 7.5
2018-03-02 CVE-2017-15130 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. Ubuntu_linux, Debian_linux, Dovecot 5.9
2017-02-17 CVE-2016-8652 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. Dovecot 5.9
2017-09-19 CVE-2015-3420 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. Dovecot, Fedora 5.9
2014-05-14 CVE-2014-3430 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. Dovecot N/A
2013-12-09 CVE-2013-6171 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. Dovecot N/A
2014-05-27 CVE-2013-2111 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. Dovecot N/A
2013-03-07 CVE-2011-4318 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. Dovecot N/A
