This update for dovecot22 to version 2.2.29.1 fixes the following issues:

This security issue was fixed:

- CVE-2017-2669: Don't double-expand %variables in keys. If dict was used as the authentication passdb, using specially crafted %variables in the username could be used to cause DoS (bsc#1032248)

Additionally stronger SSL default ciphers are now used.

This non-security issue was fixed:

- Remove all references /etc/ssl/certs/. It should not be used anymore (bsc#932386)

More changes are available in the changelog. Please make sure you read
README.SUSE after installing this update.
