Re: CVE request: Dovecot remote DoS on TLS connections

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

The current Dovecot (2.2.16) imap/pop3 server has an issue that
handshake failures will lead to a crash of the login process.

can cause the imap-login
and pop3-login processes to crash on handshake failures

An example where this is triggered is if the server is configured to
not allow SSLv3 connections and a client tries to connect with SSLv3
only.

The reason is that the error handling routine will try to finish the
handshake and that will crash. Details here:
http://dovecot.org/pipermail/dovecot/2015-April/100618.html

Use CVE-2015-3420.
