Changes Since 3.0.2
===================


Security fixes
--------------

An authenticated non-admin IMAP user could overwrite an arbitrary file
(subject to cyrus user permissions) with specially crafted SYNCAPPLY,
SYNCGET or SYNCRESTORE commands.

This issue was introduced with commit 152f59c and affects all releases
from the 3.0 series prior to this.  2.5 and earlier are not affected.

It is fixed by commits 53c4137 and 5edadcf.


Other changes
-------------

* Improved JMAP support

* imapd client_id log lines now include the session id


Bug fixes
---------

* Fixed: lmtpd no longer crashes due to uninitialised quotadb

* Fixed Issue #1434: buffer overflow in auth_pts from too-long
  imapd.conf value

* Fixed Issue #1090: non-standard NO response to ID command

* Fixed: uninitialised buffer in ischedule

* Fixed: replication desyncronisation when only last_uid field
  changes

* Fixed Issue #2076: IMAP LIST was unnecessarily dependent on PCRE

* Fixed Issue #1437: buffer overflow in mupdate-client from too-long
  imapd.conf value

* Fixed Issue #2080: crash in cyrdump due to uninitialised mboxname

* Fixed: installed arrayu64.h and strarray.h no longer depend on
  util.h

* Fixed: backup staging files are now cleaned up on signal shutdown

* Fixed: backup no longer re-uses reserve partition as staging path


Erratum
-------

Earlier release notes from the 3.0 series stated that the default
value of the "virtdomains" option had changed from "off" to "userid".
This is not the case: the default is still "off", and will remain so
for the life of the 3.0 series.
