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 'tlsversions' 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 'tlsversions: tls10 tls11 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)
