   An update that solves four vulnerabilities and has one
   errata is now available.

Description:


   This update for cyrus-imapd fixes the following issues:

   - Previous versions of cyrus-imapd would not allow its users to disable
     old SSL variants that are vulnerable to attacks like BEAST and POODLE.
     This patch adds the configuration option 'tls_versions' to remedy that
     issue. Note that users who upgrade an existing installation will *not*
     have their imapd.conf file overwritten, i.e. their IMAP server will
     continue to support SSLv2 and SSLv3 like before. To disable support for
     those protocols, edit imapd.conf manually to include "tls_versions:
     tls1_0 tls1_1 tls1_2". New installations, however, will have an
     imapd.conf file that contains these settings already, i.e. newly
     installed IMAP servers do *not* support unsafe versions of SSL unless
     that support is explicitly enabled by the user. (bsc#901748)

   - An integer overflow vulnerability in cyrus-imapd's urlfetch range
     checking code was fixed. (CVE-2015-8076, CVE-2015-8077, CVE-2015-8078,
     bsc#981670, bsc#954200, bsc#954201)

   - Support for Elliptic Curve Diffie–Hellman (ECDH) has been added to
     cyrus-imapd. (bsc#860611)
