Descriptions

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 1.1 anterior a 2.2.13 y dovecot-ee anterior a 2.1.7.7 y 2.2.x anterior a 2.2.12.12 no cierra debidamente conexiones antiguas, lo que permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de una negociación SSL/TLS incompleta para una conexión IMAP/POP3.

Dovecot is an IMAP server, written with security primarily in mind, for Linux and other UNIX-like systems. It also contains a small POP3 server. It supports mail in both the maildir or mbox format. The SQL drivers and authentication plug-ins are provided as subpackages. It was discovered that Dovecot did not properly discard connections trapped in the SSL/TLS handshake phase. A remote attacker could use this flaw to cause a denial of service on an IMAP/POP3 server by exhausting the pool of available connections and preventing further, legitimate connections to the IMAP/POP3 server to be made.
