Ubuntu Security Notice USN-3998-1
May 30, 2019

evolution-data-server vulnerability
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Evolution Data Server would sometimes display email content as encrypted
when it was not.

Software Description:
- evolution-data-server: Evolution suite data server

Details:

Marcus Brinkmann discovered that Evolution Data Server did not correctly
interpret the output from GPG when decrypting encrypted messages. Under
certain circumstances, this could result in displaying clear-text portions
of encrypted messages as though they were encrypted.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
  evolution-data-server           3.28.5-0ubuntu0.18.04.2

  libcamel-1.2-61                 3.28.5-0ubuntu0.18.04.2
  libebackend-1.2-10              3.28.5-0ubuntu0.18.04.2
  libedataserver-1.2-23           3.28.5-0ubuntu0.18.04.2
