#	CVE ID	CWE ID	# of Exploits	Vulnerability Type(s)	Publish Date	Update Date	Score	Gained Access Level	Access	Complexity	Authentication	Conf.	Integ.	Avail.
1	CVE-2019-11500	787		Exec Code	2019-08-29	2019-09-06	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
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.
2	CVE-2019-10691	287			2019-04-24	2019-07-12	5.0	None	Remote	Low	Not required	None	None	Partial
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.
3	CVE-2019-7524	119		Overflow	2019-03-28	2019-06-13	7.2	None	Local	Low	Not required	Complete	Complete	Complete
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.
4	CVE-2019-3814	295			2019-03-27	2019-06-13	4.9	None	Remote	Medium	Single system	Partial	Partial	None
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.
5	CVE-2017-15132	772			2018-01-25	2019-10-09	5.0	None	Remote	Low	Not required	None	None	Partial
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.
6	CVE-2017-15130			DoS	2018-03-02	2019-10-02	4.3	None	Remote	Medium	Not required	None	None	Partial
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.
7	CVE-2014-3430	287		DoS	2014-05-14	2017-12-28	5.0	None	Remote	Low	Not required	None	None	Partial
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.
8	CVE-2013-6171	287		Bypass	2013-12-09	2018-03-15	5.8	None	Remote	Medium	Not required	Partial	Partial	None
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.
