evolution-data-server vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS


Evolution Data Server could be made to expose sensitive information over the network.

Software Description

  • evolution-data-server - Evolution suite data server


Jon Kristensen discovered that Evolution Data Server would automatically downgrade a connection to an IMAP server if the IMAP server did not support SSL. This would result in the user’s password being unexpectedly sent in clear text, even though the user had requested to use SSL.
