Comment 5 Timotheus Pokorra 2016-01-02 15:22:14 UTC

Mono in Fedora Rawhide has now been updated to 4.2.1, which fixes the security issue for Fedora Rawhide as well.

Comment 6 Timotheus Pokorra 2016-01-02 15:22:28 UTC

For Fedora 22, Mono 2.10, there are probably far too many security issues, and it fails to build. https://bugzilla.redhat.com/show_bug.cgi?id=1222814

Comment 7 Fedora End Of Life 2016-11-24 14:27:24 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bug reports from releases that are no longer maintained.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.
