CVE-2014-3430 Dovecot vulnerability
Title: Dovecot vulnerability
Summary: Dovecot could be made to stop responding if it received specially crafted
network traffic.
It was discovered that Dovecot incorrectly handled closing inactive SSL/TLS
connections. A remote attacker could use this issue to cause Dovecot to
stop responding to new connections, resulting in a denial of service.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2014-3430 dovecot: denial of service through maxxing out SSL connections
As reported on oss-sec [1]:
There's an upper limit to how many IMAP/POP3 connections can exist that haven't logged in (and separate
limits for post-login). Normally when this limit is reached, the oldest connection gets disconnected.
There is of course some potential to try to DoS Dovecot by doing a lot of IMAP/POP3 connections, but because
the oldest connection always gets destroyed this requires quite a lot of activity from the attacker.
This "destroy oldest connection" however hasn't been working in v1.1+ releases for connections that have
started SSL/TLS handshake, but haven't finished it. So an attacker could just do a bunch of TCP
connections to port 993 and leave them hanging around and Dovecot would pre
