The Cyrus team is proud to announce the immediate availability of a new version of Cyrus IMAP: 2.5.15
This release contains a fix for CVE-2019-19783, a privilege escalation vulnerability that permits creation of arbitrary mailboxes using the 'fileinto' directive in user sieve scripts. If you allow your users to upload custom sieve scripts, and if you have the 'anysievefolder' option enabled, 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.)
