Red Hat Security Advisory 2014-0790-01
Posted Jun 25, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-0790-01 - 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.

contain a backported patch to correct this issue. After installing the
updated packages, the dovecot service will be restarted automatically.
