Description Nikos Mavrogiannopoulos 2015-01-06 12:50:42 UTC 
Please convert to use the system's crypto policy for SSL and TLS:
https://fedoraproject.org/wiki/Packaging:CryptoPolicies

If this program is compiled against gnutls, change the default priority string to be "@SYSTEM" or to use gnutls_set_default_priority().

If this program is compiled against openssl, and there is no default cipher list specified, you don't need to modify it. Otherwise replace the default cipher list with "PROFILE=SYSTEM".

In both cases please verify that the application uses the system's crypto policies.

If the package is already using the system-wide crypto policies no action is required, the bug can simply be closed.
Comment 1 Jason Tibbitts 2015-03-03 23:56:46 UTC 
cyrus-imapd calls SSL_CTX_set_cipher_list with a value that comes purely from end-user configuration:

    cipher_list = config_getstring(IMAPOPT_TLS_CIPHER_LIST);
    if (!SSL_CTX_set_cipher_list(s_ctx, cipher_list)) {
        syslog(LOG_ERR,"TLS server engine: cannot load cipher list '%s'",
               cipher_list);
        return (-1);
    }

If this is not specified, the string "DEFAULT" is used.  Is that sufficient (i.e. is the default cipher list compiled into openssl OK here) or does that need to be changed?
Comment 2 Nikos Mavrogiannopoulos 2015-03-04 06:40:10 UTC 
Then I believe it should be sufficient to set the Fedora configuration file to contain: "PROFILE=SYSTEM" as the default configured string.
Comment 3 Jan Kurik 2015-07-15 14:35:32 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

More information and reason for this action is here:
https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
Comment 4 Fedora End Of Life 2016-11-24 11:21:42 UTC 
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 5 Jason Tibbitts 2016-12-21 23:17:30 UTC 
This is actually done in the current rawhide package.  The default provided configuration file includes:

# Support system-wide crypto policy
# https://fedoraproject.org/wiki/Packaging:CryptoPolicies
# https://bugzilla.redhat.com/show_bug.cgi?id=1179212
# Comment out the below line to revert to the compiled-in default of "DEFAULT".
tls_ciphers: PROFILE=SYSTEM
