Security update for cyrus-imapd SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2016:1457-1 Final 1 1 2016-05-31T16:39:22Z current 2016-05-31T16:39:22Z 2016-05-31T16:39:22Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for cyrus-imapd - Previous versions of cyrus-imapd would not allow its users to disable old protocols like SSLv1 and SSLv2 that are unsafe due to various known attacks like BEAST and POODLE. https://bugzilla.cyrusimap.org/show_bug.cgi?id=3867 remedies this issue by adding the configuration option 'tls_versions' to the imapd.conf file. Note that users who upgrade existing installation of this package will *not* have their imapd.conf file overwritten, i.e. their IMAP server will continue to support SSLv1 and SSLv2 like before. To disable support for those protocols, it's necessary to edit imapd.conf manually to state '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 SSLv1 and SSLv2 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.
