The Cyrus team is proud to announce the immediate availability of a new version of Cyrus IMAP: 2.5.13

This release contains a fix for CVE-2019-11356, a buffer overrun vulnerability in the httpd daemon.  If you compile cyrus with HTTP support enabled and your cyrus.conf contains SERVICES entries that run the httpd daemon, you will need this upgrade.

I'm trialling hosting the release files using Github's releases feature.  Please use the Github download links if possible, and advise if you have any problems!  (It may even download faster due to Github's content delivery network.)

Please consult the release notes before upgrading to 2.5.13:

And join us on Github at to report issues, join in the deliberations of new features for the next Cyrus IMAP release, and to contribute to the documentation.

On behalf of the Cyrus team,

Kind regards,

ellie timoney
