    3. Description:
    
    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. (CVE-2014-3430)
    
    All dovecot users are advised to upgrade to these updated packages, which
    contain a backported patch to correct this issue. After installing the
    updated packages, the dovecot service will be restarted automatically.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
